Abstract
A current source inverter power supply for an ozone generator which results in improved efficiency and reliability in operation of such generators has an AC/DC converter coupled through a large inductance to a DC/AC inverter that, in turn, is coupled at its output to the primary of a high voltage transformer. Such transformer has an air gap in its core to supply the electrical characteristics necessary for resonance with the load which is capacitive in nature. Thyristors in the inverter are naturally commutated so the switching frequency is close to, but slightly above, the natural resonant frequency of the inverter/transformer/ozone generator circuit.
