Abstract
A wide input voltage range power converter circuit in a one-stage-two-switch configuration has a power input terminal, a switch node connected to the power input terminal, a transformer, two electronic switches, a pulse width modulation (PWM) circuit, and an output circuit. An input side of the transformer has a first winding and a second winding that are connected to the switch node. An output side of the transformer has an output winding. A turns ratio between the first winding and the output winding is different from a turns ratio between the second winding and the output winding. The two electronic switches are respectively connected to the first winding and the second winding in series. The PWM circuit is connected to the power input terminal and control terminals of the two electronic switches. The output circuit is connected to the output winding.
