Abstract

Abstract 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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 134 words
A power supply for supplying a high AC voltage to an ozone generator from a low voltage AC source, said supply comprising: a magnetic-leakage type transformer and a saturable core inductor, said transformer having a primary winding which is connected in series with a first winding of said inductor and the series combination connected to said low voltage AC source, a secondary winding of said transformer being connected to said ozone generator; said inductor having a second winding which is supplied with a continuous DC current so as to control the inductance value of said inductor by varying the amount of saturation of said saturable core of said inductor; wherein the magnitude of said high AC voltage supplied to said ozone generator is varied in accordance with the magnitude of said continuous DC current.
Claim 2
Dependent Claim 134 words
