A 30-volt 10-ampere regulated power supply using the variable output transistor oscillator with current transformer

A previous unpublished paper by the author derived the design equations for the transistor saturable current transformer amplifier. In that discussion, sample calculations were made and an amplifier designed. Measured values were compared with those calculated. It is a short step to use the amplifier previously designed in a direct output power supply to provide a constant 30 volts up to 10 amperes. A current limiting circuit was added to the circuit to restrict output current under overload conditions.
