A DC-to-DC converter comprises a converter section and a controller section. The converter section comprises a primary section and a secondary section. The primary and secondary section includes MOSFET switches. The controller section is coupled to the converter section and comprises a pulse width modulation (PWM) section and a delay section. The PWM section comprises an error amplifier configured to generate an error signal representative of a variance between an output voltage of the converter section and a reference voltage and a PWM configured to produce a PWM signal based on the error signal. The delay section comprises of delay circuits configured to generate delayed output signals from the PWM signal and power switching device drivers coupled to the delay circuits and configured to receive the delay output signals and generate a controlled signals to control the on/off state of the MOSFET switches.

Control circuit for lossless switching converter

A voltage reference circuit receives an input voltage through a first port and a time varying input signal through a second port. The voltage reference circuit includes a switching circuit that is responsive to the first and the second ports and that generates an AC signal from the input voltage. The voltage reference circuit further includes a voltage multiplier circuit, coupled to the switching circuit that receives the AC signal and creates a DC signal with a selected voltage level. The voltage reference circuit further includes a voltage regulator, coupled to the voltage multiplier circuit that regulates the DC signal from the voltage multiplier circuit. A regulated output voltage is provided through an output port.
