Linear output LED drive power supply of capacitanc

The utility model provides a linear output LED drive power supply of capacitanc. This power comprises input L and N, rectifier circuit, control circuit, charging and discharging circuit, output circuit. After charging to at least one charging capacitor through a control circuit charging tube of control (MOSFET), the electric charge of being saved by a discharge tube release charging capacitor discharges to discharge output capacitance ware and load. Realize voltage conversion under the condition of no transformer, improved the alternating current power factor and alternating current to the galvanic conversion efficiency of power. When utilizing the condenser for the definite value, input voltage and output are linear relation's characteristic, have permanent power characteristic at certain output within range, have avoided the LED light because of the damage that voltage variation caused, have prolonged the life of LED light. 本实用新型提供一种电容式线性输出LED驱动电源。该电源由输入端L和N、整流电路、控制电路、充放电电路、输出电路构成。通过控制电路控制一只充电管(MOSFET)对至少一只
