Abstract:
An output regulation circuit of a power converter without current sensing loss includes a transforming circuit to receive a proportional voltage from the primary winding of the power converter during the on-time period of the power switch. The first proportional voltage is transformed to a charging current signal to charge an energy storage device. Thus, the circuit controls the power switch according to a voltage limited signal of the energy storage device.
