Abstract

A hybrid power converter includes a switching circuit, an LC circuit, and a detection circuit. The switching circuit includes three or more switching transistors in series that may turn on or off according to a switching cycle to generate a series of voltage pulses at an output port across one of the switching transistors. The LC circuit may be coupled to the output port of the switching circuit to receive the series of pulses and to generate an inductor current in the LC circuit. The inductor current may charge a capacitor of the LC circuit to generate an output voltage of the hybrid power converter. The detection circuit may be coupled to the switching circuit and may generate a low frequency portion of the inductor current based on one or more currents of the switching transistors to adjust the switching cycle based at least on the low frequency portion.
