The invention discloses a new energy automobile DC charger output regulation and control circuit and a power supply protection control method. The circuit comprises a first filtering module, a voltageregulating module, a second filtering module, an over-current protection module, a resonance circuit module and a voltage stabilization constant-current output control module. An inductor L1 and a capacitor C1 in the first filtering module form a filtering circuit, and ripples in rectified output voltage are filtered out. A pin 1 of a variable resistor RV2 is moved in the voltage regulating module to change the resistance value of the resistor so as to reduce the passing voltage. An inductor L3 and an inductor L4 in the second filtering module are used for screening and filtering the adjustedelectric signals. A resistor R9 in the overcurrent protection module absorbs the electric energy stored in the capacitor C10 to prevent overlarge discharge current. A triode Q2 in the resonance circuit module controls voltage conduction to increase resonance impedance so as to realize voltage gain. A bidirectional silicon controlled rectifier U4 in the voltage stabilization constant current output control module receives an electric signal output by a charger through a pin 1 to realize voltage conduction so as to protect and control an output power supply.
