Blog dell'azienda Mingjiada Supplies Infineon IGBT Discrete Devices (TRENCHSTOP IGBT7/5) for Solar Inverters and Uninterruptible Power Supply Applications

Dedicated to Solar Converters and UPS (Uninterruptible Power Supply) Systems: Infineon IGBT Discrete Devices (Complete Overview of Models Available from Mingjiada)

Application Scenarios and IGBT Technical Requirements

Solar converters (photovoltaic inverters) and UPS (uninterruptible power supply) systems are currently the two fastest-growing application markets in the power electronics sector. Both types of system share highly consistent core requirements for power switching devices: high conversion efficiency, low conduction losses, excellent thermal stability and long-term reliability.

Solar photovoltaic inverters need to minimise losses during the DC-AC conversion process to enhance the system’s power generation efficiency. Single-phase string inverters typically require IGBTs with a voltage rating of 650 V to 1,200 V and a switching frequency ranging from 15 kHz to 120 kHz, whilst also demanding extremely low saturation voltage drops and switching losses. Uninterruptible power supplies (UPS) place additional demands on the dynamic response speed and short-circuit withstand capability of the devices; in particular, during the instantaneous transition from mains power to battery power, IGBTs must withstand significant current surges.

Infineon’s TRENCHSTOP™ series of IGBTs utilises ultra-thin trench gate field-stop technology to achieve a precise balance between on-state and switching losses, and has become the benchmark choice for the aforementioned application areas.

Infineon’s 750V TRENCHSTOP™ IGBT7 H7 DTO247 discrete transistors feature a package size twice that of the standard TO-247, enabling them to replace multiple low-current TO-247 IGBTs connected in parallel, thereby simplifying parallel circuit design and reducing system complexity. With rated currents ranging from 200A to 350A, this series is specifically designed for high-current solar inverters, UPS systems and energy storage systems.

Selection Guidelines and Supply Information

In the two application categories mentioned above, the 650V-rated IGBTs are primarily intended for the MPPT stage of photovoltaic inverters and the PFC/inverter stages of small-to-medium-power UPS systems, whilst the 1200V-rated IGBTs are suitable for the power conversion stages of 1100V DC bus photovoltaic systems and three-phase UPS systems. Compared to the previous-generation 5 Series, the TRENCHSTOP™ IGBT 7 Series offers lower saturation voltage drops and superior high-temperature performance at the same current rating, making it suitable for new designs with higher requirements for efficiency and power density.
