Abstract
A circuit to provide power to a load includes a first diode having a cathode connectable to a second terminal of a PTC thermistor and an anode connectable to a first node of the load. The anode of a second diode is connectable to the second terminal of the PTC thermistor and the cathode thereof is connectable to a second node of the load. The anode of a third diode is connectable to the anode of the first diode and the first node of the load and the cathode thereof is connectable to a neutral line of an AC power source. The anode of a fourth diode is connectable to the neutral line of the AC power source and the cathode thereof is connectable to the cathode of the second diode and the first node of the load.
