Abstract

The variable, stabilised d.c. voltage transformer, for power supplies, has the power supply full wave rectifier feeding a DC/AC converter. The converter output is rectified by a controlled rectifier and passed over a voltage-overload protection circuit to the power supply output terminals. A sawtooth generator produces a control voltage which is converted into an a.c. triangular-wave pulse sequence with the help of a trigger circuit synchronised to the controlled rectifier control signals. The wave converter output is itself converted into a.c. rectangular pulses and used to control the DC/AC converter. A further voltage overload protection circuit is connected between the first rectifier and the a.c. supply.
