To produce a high current carring inductor with a high inductance value in space normally too small, a transformer (20) is chosen which meets space requirements and has a primary winding (18) of sufficient current capacity, but too little inductance. A bidirectional current source (30) drives the secondary winding (19) under control of a feedback circuit (40) in response to sensed primary winding current to effectively multiply the primary winding inductance. |
