Abstract

Hysteresis current control is widely used in active power filter´s current control. Principle of variable-band hysteresis current control, relationship between compensation capacity of hysteresis and switching frequency are given in this paper. Taking into account the fixed-band hysteresis current control, a control strategy based on command current and current error is proposed which is a variable-band current control strategy based on fuzzy rules and realized by fuzzy controller. Power electronics model is built by PSIM software and logical control circuit is built according to the rules. Simulation results indicate that the hysteresis has better compensation capacity than fixed-band hysteresis and deduces switching frequency.
