Abstract
The utility model relates to an electronic transformer for the electric shaver, comprising a direct current high-voltage power supply circuit, a high frequency oscillator, a commutation diode and a filtering capacitor. The VT1, the C2, the VT3, and the C3 of the high frequency oscillator continuously works, and provides continuous alternating current to the transformer, and causes the T1C coil of the transformer to continuously alternate the magnetic field and mutually induce. The T1D secondary coil generates the alternating voltage, and the alternating voltage is supplied for the drive electric motor to work after rectified and filtered. The utility model overcomes the defect that the dry cell or the chargeable battery shaver has high use cost and low reliability, and has the advantages of low consumption, high efficiency, high stability and obvious energy saving.
