<p>An ozonator power supply including a step-up transformer having one end of its primary winding (8) connected to one side of an AC supply (2), its other end connected to the other side of the AC supply via a pair of switches (12, 14) connected in antiparallel, and a controller (26) for providing switching pulses to said switches for making them conductive during variable portions of alternate half cycles of the AC voltage provided by said supply. An inductor (10) is included in the circuit with the primary or secondary winding of the transformer that resonates with the capacitive impedance (CD and CG) of an ozonator (18), for presenting a substantially non-reactive load to said AC supply (2).</p> |
