ABSTRACT:
A controlled single-ended down converter comprises a transformer of d.c. separation of the input circuit and the output circuit, a switching element controlled in pulse width in the input circuit and a rectifier diode as well as a fly-wheel diode in the output circuit. During the conducting phase of the switching element, the transformer takes up magnetization energy. This energy is demagnetized through the barrier layer capacitance of the rectifier diode during the cut-off phase.
