I. EPC GaN Field-Effect Transistors: Core Components for High-Performance Power Conversion

EPC GaN field-effect transistors (eGaN® FETs) are enhancement-mode gallium nitride high-electron-mobility transistors built on a silicon substrate, and serve as the core components of EPC’s power solutions. Distinct from the physical structure of traditional silicon MOSFETs, eGaN® FETs have no reverse recovery charge, lower gate-source capacitance and lower on-state losses. They combine four core advantages: high frequency, high efficiency, miniaturisation and high reliability. They are directly compatible with traditional MOSFET application circuits; replacement and upgrading require no significant changes to hardware design, making them suitable for large-scale mass production.

1. Core Technical Advantages

Compared with silicon-based devices, EPC’s GaN field-effect transistors achieve comprehensive breakthroughs in core performance: switching speeds are increased by more than 10 times, supporting high-frequency operation in the MHz range and significantly reducing the size of passive components such as power transformers and capacitors; extremely low on-resistance and switching losses effectively reduce the power consumption of the entire system, with power conversion efficiency improved by 3–8 per cent; The absence of reverse recovery characteristics completely eliminates switching oscillations and reverse conduction losses, significantly reducing electromagnetic interference (EMI) and simplifying the system’s filtering design; the device structure is streamlined, with highly miniaturised packaging, resulting in a power density far exceeding that of comparable silicon MOSFETs. Furthermore, the entire product range is manufactured using mature silicon production lines, balancing high performance with low cost, and is suitable for both consumer-grade mass applications and high-end, demanding scenarios.

2. Product Portfolio and Key Features

EPC’s GaN field-effect transistors cover the entire voltage range from 15 V to 350 V, constituting the most comprehensive range of off-the-shelf GaN power devices on the market. The portfolio comprises three major categories: general-purpose commercial-grade, automotive-grade and aerospace radiation-hardened-grade, meeting the reliability requirements of various applications. Mainstream mass-produced models, such as the EPC23101 and EPC800X series, combine low on-resistance with low gate charge, making them suitable for various power topologies including low-voltage, high-current applications, high-frequency rectification and inversion. The radiation-hardened series, specifically developed for extreme environments such as aerospace and satellites, offers exceptional resistance to radiation, high temperatures and shock, enabling long-term, stable operation under demanding conditions.

3. Typical Application Scenarios

Widely used in fast-charging power supplies for consumer electronics, laptop adaptors, DC-DC buck/boost modules, BLDC motor drives, robotic power systems, drone power supplies, automotive low-voltage power systems, and precision power supplies for aerospace applications, these devices are the preferred core components for high-frequency, miniaturised power conversion equipment.

II. EPC GaN Gate Drivers: Dedicated High-Speed Drive Cores for GaN Devices

The high-frequency performance of GaN field-effect transistors can only be fully realised with a dedicated gate driver chip. Traditional silicon-based MOS drivers fail to meet the operational requirements of GaN devices in terms of speed, timing and voltage compatibility. EPC’s in-house developed GaN gate driver is tailor-made for eGaN® FETs. Acting as the crucial link between control signals and GaN power transistors, it precisely matches the high-speed switching characteristics of GaN devices, ensuring the stable, efficient and reliable operation of the power circuit.

1. Core Technical Advantages

EPC’s GaN gate drivers feature ultra-high switching speeds and extremely short propagation delays, making them perfectly suited to the MHz-level high-frequency operating modes of GaN devices and fully utilising GaN’s advantages of high frequency and low loss. They integrate functions such as programmable dead-time, under-voltage lock-out protection and independent pull-up/pull-down outputs, which effectively mitigate issues such as conduction crosstalk and false triggering in GaN devices, thereby enhancing system stability; Certain high-end models incorporate an on-chip linear regulator, enabling direct compatibility with wide-voltage inputs, simplifying peripheral circuit design and reducing PCB footprint. Furthermore, the driver’s output drive capability is precisely matched to the entire range of EPC GaN power transistors, ensuring accurate and highly consistent drive timing, which effectively reduces switching losses and EMI interference.

2. Core Product Categories

EPC GaN gate drivers are divided into two main series: commercial general-purpose and aerospace radiation-hardened. Mainstream commercial models are suitable for conventional applications such as fast charging, industrial power supplies and motor drives; the radiation-hardened series, such as the EPC7009L16SH and FBS-GAM02P-R-PSE, are specifically developed for space satellites and military equipment. They offer excellent radiation resistance, wide operating temperature ranges and high environmental adaptability, enabling stable operation in extreme space environments and scenarios with drastic temperature fluctuations. The product range includes single-output and multi-output models, compatible with single-phase and three-phase power topologies, to meet the requirements of equipment across different power ratings.

3. Typical Application Scenarios

Primarily used in conjunction with the full range of EPC GaN field-effect transistors, these products are applied in high-frequency switching power supplies, three-phase BLDC motor drive inverters, industrial high-frequency rectification systems, drone power drive modules, and precision power systems for aerospace. They are essential supporting chips for realising high-performance GaN power systems.

III. EPC GaN Controllers: The Integrated Intelligent Power Control Core

EPC GaN controllers are integrated intelligent control chips that combine logic control, level conversion, timing management and drive control. Unlike standalone gate drivers, they not only provide drive functionality but also incorporate complete power loop control logic, enabling the direct output of precise power switch control signals. When paired with GaN power devices, they form a power conversion system with an extremely simplified architecture. Some high-end models integrate the power stage, driver stage and control stage, realising a single-chip power solution that significantly simplifies circuit design.

1. Key Technical Advantages

High integration is the key highlight of EPC’s GaN controllers. By integrating multiple functions—including input logic interfaces, high-voltage level shifting, synchronous bootstrapping, gate driving and loop control—they eliminate the need for additional driver and control chips, significantly reducing the number of peripheral components, simplifying PCB layout and lowering overall system costs; Built-in precision timing control algorithms adaptively match the switching characteristics of GaN devices and optimise dead-time, further reducing system losses; support for high-frequency operation and wide input voltage ranges accommodates power requirements across multiple scenarios, whilst integrated protection functions—including overvoltage, overcurrent, undervoltage and over-temperature protection—ensure safe and stable system operation.

2. Key Features of Benchmark Products and Solutions

GaN controllers, exemplified by the EPC33110, represent EPC’s new generation of core products. The EPC91132 three-phase BLDC motor drive inverter reference design, built around this chip, is currently one of the smallest GaN motor drive solutions available and is specifically optimised for robots, drones and small servo equipment. Furthermore, EPC’s ePower power stage chips integrate high-frequency GaN power switches with controllers and drivers onto a single chip, achieving a unified control, drive and power output solution. This drastically reduces equipment size whilst enhancing power density and system reliability. The entire range of controllers supports standardised design, accompanied by comprehensive design models, evaluation boards and application manuals, significantly shortening customers’ R&D cycles.

3. Typical Application Scenarios

These solutions are particularly well-suited to applications requiring miniaturisation, high power density and high reliability, including humanoid robots, drones, portable servo equipment, small industrial inverters, high-end consumer fast chargers and automotive micro-power systems. They are especially well-suited to intelligent power equipment that requires lightweight construction, high precision and high-frequency operation.
