In order to make the collector voltage distribution more balanced when multiple IGBT devices are connected in series, so as to realize the better application of IGBT in high voltage, large capacity and high power occasions. Based on the research of various IGBT series voltage equalization technologies, a new circuit combining inductance clamp circuit and active clamp circuit is proposed to realize static and dynamic voltage equalization, and the working principle of each part of the circuit is discussed. Detailed analysis and explanation. And using LTspice simulation software, a new voltage equalization simulation circuit is established. The simulation results show that the new voltage equalization circuit not only achieves a good voltage equalization effect when the IGBT drive signals are synchronized, but also maintains the voltage equalization well when the signals are not synchronized, and can also significantly suppress the overvoltage in the switching state. Feasibility of new voltage equalization circuits.
