ABSTRACT:
A power supply comprises a bridge rectifier with an input and an output, the input of the bridge rectifier coupled to an AC power supply signal, the output comprising positive and negative terminals; a first inductor comprises a first terminal and a second terminal, the first terminal coupled to the positive terminal of the output of the bridge rectifier; a first switch comprises a first terminal, a second terminal and a control terminal, the first terminal of the switch coupled to the second terminal of the first inductor, the second terminal of the switch coupled to the negative terminal output of the bridge rectifier and the switch being switched on and off at a first duty cycle according to a signal received at the control terminal; a first diode comprising an anode terminal and a cathode terminal, the anode terminal coupled to the first terminal of the switch; a first capacitor comprises a first terminal and second terminal, the first terminal coupled to the cathode of the first diode and the second terminal coupled to the negative terminal of the output of the bridge rectifier, the first capacitor adapted to supply power to a load coupled to the power supply; and a pulse width modulation controller with a first input and a first output, the first input of the pulse width modulation controller coupled to the first terminal of the first capacitor and the first output of the pulse width modulation controller coupled to the control terminal of the switch.
