This paper adopts PAM+PWM hybrid modulation method in a five cascade SVG (Static Var Generator). Four PAM (Pulse Amplitude Modulation) units output a voltage which is of fixed amplitude and in phase with the system voltage; and current direct controlling method was applied in the only PWM (Pulse Width Modulation) unit to adjust the output reactive current. To balance the DC-side voltage, pulses rotated...
A novel hybrid active power filter (HAPF) topology is proposed, which shows advantages of the conventional HAPF and the filter in terms of reduced dc-link voltage, lower switching ripples, and less electromagnetic interference injection. To enhance the noise rejection capability of the digital controller, the resetting filters (RFs) are utilized as prefilters before the analog/digital sampling...
