Abstract
A Pulse Frequency Modulation (PFM) with Zero-Current-Switching (ZCS) flyback inverter is proposed in this paper. By using half-wave quasi-resonant ZCS flyback resonant converter and PFM control, this topology significantly alleviates switching losses. A detailed analysis revealed nonlinearity in the power stage when the secondary side inductance gets smaller. A modified structure with a secondary side MOSFET is also proposed to solve this issue. Finally, the experimental results of 250W converter are provided.
