Claim:
1. A regulating power converter comprising: a transformer; a charging circuit connecting with said transformer, and charging said transformer whereby said transformer generates a secondary voltage; a discharging circuit connecting with said transformer, and discharging said secondary voltage to generate an output voltage and a secondary current, and said charging circuit retrieves time information from said secondary voltage through said transformer, and said charging circuit drives said transformer to regulate said output voltage according to said time information, and said time information is a first time point that said secondary current becomes zero after a second time point that said discharging circuit starts to generate said secondary current, and a time duration between said first and second time points is fixed, and said transformer has a primary winding, a secondary winding and an auxiliary winding, and said discharging circuit is connected with said secondary winding, and said primary winding is connected with a voltage terminal, and said discharging circuit further comprises a loading capacitor connected with said secondary winding, and said secondary current is sent to said loading capacitor whereby said output voltage is applied across said loading capacitor, and said charging circuit further comprises:
