Abstract

Firstly, according to the topology of conventional chopper cascade speed system to analyze the transient process of main loop during of contactor operation when device failure. Because the contactor action requires a longer time, Equipment is vulnerable to the impact of high voltage, high current during the contactor action, and cause damage to power electronic devices. For contactors drawbacks, the main circuit topology with electronic protection circuit is designed. Then analyze transient process of conventional chopper cascade speed system and chopper cascade speed system with electronic protection circuit under high voltage power failure conditions, and theoretics is detailedly deduced. The basis of theoretical analysis under high-voltage power failure condition is get. Finally, simulation model of conventional chopper cascade speed system and with electronic protection circuit is built respectively in Matlab, and research on simulation under high-voltage power failure condition. Simulation results verify the correctness of theoretical analysis and derivation, and show that electronic protection circuits effectively solve the problem of high-voltage power failure under active inverter structure and inverter subversion.
