Real-time control method for sinusoidal output voltages in series-resonant HF-linked DC-AC converter

This paper proposes a real-time control method of a series resonant high frequency link DC/AC power converter and a feedback control method of its output voltage waveform. An approximate analysis of the converter is performed for obtaining an equivalent circuit. Real-time feedback control for sinusoidal voltage waveform is realized using the equivalent circuit. Experimental results in the case of linear and nonlinear loads and presented to confirm the usefulness of the proposed control algorithm.<>
