Power supply for ozone generator

摘要

A power supply for an ozone generator utilizes a magnetic-leakage type step-up transformer in series with a saturable core inductor which are connected in series across a low voltage AC source. The secondary of the transformer is connected to the ozone generator and the inductor has a control winding which is connected to a continuous (i.e. DC) current source whose value controls the inductance of the inductor. Since the voltage of the low voltage AC source is divided between the inductor and the transformer, the DC current effectively controls the magnitude of the voltage across the transformer primary and thereby controls the high AC voltage supplied to the ozone generator.
