In order to improve the accuracy of high and low voltage ride through test of low voltage auxiliary inverter and effectively solve the problems of large test voltage error and long voltage conversion time, on the basis of the existing test equipment, a more perfect precision control strategy was proposed. By using fuzzy self-tuning Proportional-Integral-Differential (PID) control algorithm to achieve accurate voltage regulation, the integrated test device of high low voltage ride through of low voltage auxiliary inverter was further improved. Through the application of simulation and field test, the effectiveness and accuracy of the precise voltage regulation control strategy were verified, which effectively reduced the voltage regulation error and can greatly shorten the voltage conversion time.
