基于IGBT串联技术的电压源变换器

With the development of insulated gate bipolar transistor (IGBT) and pulsewidth modulation control strategy, the voltage source converter (VSC) is getting more and more popular, which can be used in high-voltage frequency converter, VSC-HVDC, FACTS, and custom power. In high voltage and high power applications, serial connection of IGBTs is a good solution to overcome the voltage limitation of the...
