摘要： Improvements in the supply of high-frequency electrical power to ozone-producing cells can be accomplished using the systems and techniques described herein. Application of a DC-DC converter operating at a switching frequency substantially greater than a load frequency, supports generation of a high-voltage AC for powering such cells, while allowing for reductions in component size and reductions in a quality factor of a load tuning circuit. Controllable power inverters used in obtaining one or more of the switching and load frequencies can be controlled using feedback techniques to provide stable, high-quality power to ozone-producing cells under variations in one or more of externally supplied power and load conditions. An inrush protection circuit can also be provided to selectively introduce a current-limiting resistance until an input DC bus has been sufficiently initialized as determined by measurements obtained from the DC bus. The current limiting resistance can be a positive-temperature coefficient thermistor.

摘要： A power system for a dielectric barrier discharge system, such as used for generating ozone, can include a full bridge inverter stage and parallel resonant tank outputting a signal for powering a dielectric barrier discharge cell stack. The inverter stage is controlled using a combination of pulse width modulation (PWM) and frequency modulation (FM) to enable soft switching through all load conditions—from full load to light load. A current control loop error amplifier compensator can provide a duty cycle adjustment signal to a phase shift PWM controller chip that generates the switching signals for the inverter stage. A feedback signal is also used to adjust a clock frequency time constant of the PWM controller chip to provide the FM. In one embodiment, the feedback signal is an output of an inverting amplifier connected at an output of the current control loop error amplifier compensator.
