ABSTRACT:
A versatile pulsed voltage resonant inverter power supply for an ozonator which results in the efficient operation thereof. A resonant inverter ozonator power supply comprises a DC power source and a DC/AC thyristor inverter coupled at its outputs to the primary winding of a high voltage transformer. The ozonator load is connected across the secondary winding of transformer and provides a discharge path during each high frequency cycle. First and second embodiments of control circuits are disclosed for generating gating control signals for the thyristors. The switching frequency at which the thyristors are triggered is selected to be lower than the circuit resonant frequency in order that the load voltage supplied by the inverter is substantially pulsed, and a pulse burst modulation mode is also disclosed.
