ABSTRACT:
A power supply/sink for use with switched inductive loads includes a transformer with a first secondary winding for generating power supply current connected in a circuit with a power supply terminal. A second secondary winding is connected in a circuit to a power sink terminal. The two secondary windings are interconnected with a controlled conduction path which is arranged to supply sink current in response to variations in the voltage at the power sink terminal.
