基于低开关损耗新型滞环PWM整流器研究
Research of New Hysteresis PWM Rectifier Based on Low Switching Losses
摘要
Abstract
According to the control requirement and actual project conditions of three-phase high power fac-tor rectifier, the low switching losses three-phase PWM rectifier which adopts hysteresis current control strat-egy based on load current feed-forward control was researched. The system not only improve the high-frequen-cy switching problem brought by conventional hysteresis control strategy, but also adopts load current feed-forward control to make the system has much lower dependence on the PI parameters of the outer voltage regu-lator than conventional hysteresis current control PWM rectifiers. The system works well even under unbal-ance power conditions. Simulation and experimental data both confirm the validity of the new control strategy.关键词
