  • Power supply including transformer-less high voltage power oscillators for ozone generation
    Patent number: 8641978
    Abstract: A transformer-less power supply is provided for ozone generation. The power supply advantageously reduces costs and increases reliability of ozone generators. The power supply provides a first AC voltage from a power source to a resonant circuit and the resonant circuit provides a second AC voltage to the ozone generating unit, the second AC voltage being greater than the first AC voltage. A controller for the power supply that adapts to the resonance of the circuit to provide control with a wide tolerance for the high Q circuit component values of the circuit.
    Type: Grant

  • Power holdup circuit
    Patent number: 6879140
    Abstract: A power holdup circuit including a monitoring circuit and a power holdup circuit. The monitoring circuit includes an average voltage comparator and an absolute voltage comparator which cooperate to detect a voltage drop in the voltage supplied by the power supply. The monitoring circuit also includes a timer to determine the time period of the voltage dropout. If a predetermined voltage dropout event occurs, the monitoring circuit generates a control signal to a switching component which activates a holdup power source. The holdup power source includes an energy storage device that stores energy to maintain the supply voltage during dropout periods.
