Prediction current injected control applied to DC-AC parallel resonant converters

The author presents the analysis, simulation, and experimental results for a DC-AC converter with a resonant parallel high-frequency link, suited to high power levels. A novel current mode control process with current prediction is introduced. It allows the regulation of the low-frequency output voltage, even in the presence of a wide variation of the HF oscillating resonant voltage. The output voltage is obtained with low distortion and good regulation.<
