Patent ID: 6975071

Claim:
A voltage booster of a headlight for increasing a voltage of the headlight; the voltage booster being connected between a power supply and a headlight; the voltage booster comprising a high frequency circuit, a voltage boost circuit, a rectified circuit, and a high frequency control circuit; wherein a DC current is supplied from the power supply end; then the current flows through two high frequency oscillators which are parallel connected and then is boosted by boosting coils; then the current is rectified by the diode as DC current and then is outputted from an output end; and wherein an over current sensing circuit is connected between the headlight and the rectified circuit; the headlight is connected to the power supply through a wire with a relay connected between the headlight and the power supply end; if the headlight is over-current, than the over current sensing circuit is interrupted so that the power is supplied to the headlight through the wire.
