Temperature control is one of the key factors for the effective operation of MOSFET or IGBT module. Although some MOSFETs are equipped with an internal temperature sensor (body diode), other methods can also be used to monitor temperature. The semiconductor silicon PTC thermistor can perform current control well, or the platinum-based or niobium-based (RTD) resistance […]

1. What is an IGBT?   One of the most important components in power electronics is the IGBT.   The so-called IGBT (Insulated Gate Bipolar Transistor) is a composite full-regulated-voltage-driven-power semiconductor device composed of BJT (Bipolar Junction Transistor) and MOS (Insulated Gate Field Effect Transistor), which has its own The feature of shutdown.   To […]

IGBT module inverter circuit design for solar photovoltaic power generation (1) Solar photovoltaic power generation harnesses sunlight to convert solar energy into electrical energy using solar arrays, specifically PV module squares. The generated direct current (DC) is then transformed into alternating current (AC) through an inverter for user consumption. Traditionally, photovoltaic power generation systems employed […]

First of all, it should be explained that SiC can also be used as an IGBT Module. There is a problem with the Mosfet of Si material, that is, the chip will become thicker if the voltage withstand capability is high, and the conduction loss is also very high. Therefore, the Mosfet of silicon material […]
