21.1 INTRODUCTION

The saturable reactor regulator, otherwise referred to as the saturable-core magnetic regulator or magnetic pulse-width modulator, as applied to high-frequency switchmode power supplies, is a relatively new development of the very well established line frequency magnetic amplifier power control technique. However, in high-frequency applications, the mode of operation is quite different.

As a result of the recent advances in magnetic materials, particularly the low-loss square-loop field-annealed amorphous alloys, these techniques are now finding interesting reapplications in high-frequency switching regulators.

The major attraction of this method of control is...
