The analysis and experiment on full-soft-switching inverter under wide-range input voltages

Batteries are widely used in quite a few areas, including in the electric auto industry. As the voltage of the batteries are ever-changing, which drops from a high value to a low value, kinds of regulators are utilized to keep the output voltage changing in an acceptable scope. However, the stress on switches produced by the currents in the circuits is much stronger than the capabilities of the switches, the strike on switches cannot be neglected as well. In this paper, it is the main content to discuss how to realize soft switching on some switches, furthermore, how to realize full soft switching on all switches. A sort of improved CUK converter and a newly-advanced neutral pointed clamped (NPC) switching voltage source (SVS) circuit are integrated, the aim to realize the soft switching on switches and better output wave is reached partly or fully in the simulation using the Pspice software. Finally, relative experiment will be made and corresponding sample will be produced.
