Hysteresis Grid Current Control Method for Active Power Filter with Self-adaptive Switching Frequency
摘要
Abstract
A novel self-adaptive hysteresis grid current control technique based on the active power balance theory for three- phase and four-wire active power filter was introduced. The algorithm changes hysteresis band according to the supply voltage, load voltage and slope of grid current wave to make the switching frequency stable. The grid current would keep dynamic stability when the load changes. The characteristic of the method is absolutely digital controlling without the traditional detection for harmonic current. Finally, the method for three-phase and four-wire active power filter current control with self-adaptive switching frequency was verified effective and feasible by simulation results of Madab.关键词
