A controller for use with a power converter including a switch configured to conduct to provide a regulated output characteristic at an output of the power converter, and method of operating the same. In one embodiment, the controller includes a linear control circuit, coupled to the output, configured to provide a first control signal for the switch as a function of the output characteristic. The controller also includes a nonlinear control circuit, coupled to the output, configured to provide a second control signal for the switch as a function of the output characteristic. The controller is configured to select one of the first and second control signals for the switch in response to a change in an operating condition of the power converter.

Controller for a power converter and method of operating the same

AC/DC power converter device comprising a full-wave rectifier (R) the output of which is applied to a direct current module which has two outputs: the main output is connected to the load via a capacitor (C1) which transfers a first power level (P1), and the auxiliary output is formed by a capacitor (C2) and a direct current converter (DC) which stores a second power (P2) and transfers it to the load during the full cycle of the input power wave (PE). As a result the second power level (P2) is continuously topping up the first power level (P1).
