Claim:
1. A power converter comprising: a single switching transistor electrically connected to a direct current (DC) power source having a first voltage level; a first inductor-capacitor circuit electrically connected to an output of the single switching transistor and configured to receive electrical power from the DC power source through the single switching transistor in response to the switching transistor being switched on, wherein the first inductor-capacitor circuit includes an inductor and a capacitor, the inductor being connected between the single switching transistor and the capacitor; and a second inductor-capacitor circuit electrically connected first inductor-capacitor circuit and configured to provide an output signal to a load; and a controller operatively connected to the single switching transistor, the controller being configured to: identify an error between the output signal and a reference signal; and adjust a duty cycle of a pulse width modulation (PWM) switching signal to switch the single switching transistor at a predetermined frequency with the adjusted duty cycle to reduce the identified error.
