Abstract
A switching regulator device for charging applications includes a transformer (18) which receives an AC input signal from an AC source (12) which is then rectified with a bridge rectifier (24). A regulation control circuit (26) is provided for regulating the output level of the bridge circuit (24) to a load (20). The regulation circuit (26) includes a switching element (62) which is operable to draw current from the AC source (12) in a periodic manner. The on/off duty cycle of the control to the switching element (62) will allow energy to be stored in a leakage inductance (36) of the transformer (18). The transformer (18) therefore comprises the switching inductance of a switching power supply with the leakage inductance (36) designed to provide adequate regulation for the voltage and current supplied to the load (10).
