Control circuit of voltage stabilizer and control method thereof

The invention discloses a control circuit of a voltage stabilizer and a control method thereof. The control circuit comprises an equivalent inductive current sensor module, a load current sensor module, a steady state judgment module, a signal distribution module, a charge balance module and n PWM (Pulse Width Modulation) controllers, meanwhile, the invention discloses a control method of the control circuit, specifically, the inductance value of an equivalent inductor in a transient state is reduced and the current rising speed of the equivalent inductor is increased by changing the conduction time sequence of a main loop switch tube when a load jumps, and meanwhile, the discharging energy and the charging energy of an output capacitor are balanced; a charge balance module in the control circuit calculates the on and off time of a switching tube, so that the output voltage and the equivalent inductive current are recovered to a steady state at the same time, and the purpose of reducing the transient response
