ABSTRACT:
A secondary switch controller has an input circuit with an inductance and a semiconductor switch and an output circuit with a rectifier and a smoothing element. A circuit for controlling operation of the secondary switch includes an internal control loop responsive to the voltage at the inductance, an external control loop responsive to the output voltage, and a current limiting circuit responsive to the current flowing through the input circuit.
