Variable duty cycle switching with imposed delay

摘要

Power conversion methods, systems, articles of manufacture, and devices are provided. The power conversion may include converting between direct current and alternating current wherein switching losses associated with latent electrical charges are reduced. Current sensing may be low-side bus reference. Solid-state implementations, code implementations, and mixed implementations are provided.

1. A power converter comprising:
a DC/AC converter circuit of switching type comprising four switches coupled to receive input voltage and configured to provide an AC output voltage; and a control circuit configured to sense an output current of the DC/AC converter and generate a command signal to trigger one or more of the switches when the sensed current falls within an upper voltage boundary and a lower voltage boundary.
