| Abstract: | Two schemes of OCC(One-Cycle Control) modulation for single-phase APF(Active Power Filter) are analyzed:the bipolar modulation and the unipolar modulation.An improved unipolar modulation scheme is presented by changing the operating process of its switching device.The equivalent circuit of system operating process is analyzed and its control objective equation is deduced.The one-cycle control circuit and logic selection circuit of driving signal for switching device are designed without transformer and adde... |
