A corona plasma cell includes a polarized electrode and a ground electrode, including a cylinder and a porous film, with the cylinder having a low profile and the polarized electrode not entering the cylinder; a corona plasma dual element including a first cell, a second cell having such a structure, which first and second cell are symmetrically arranged; and finally a plasma reactor including a plurality of cells or dual elements.

An ozone generator includes at least four independent ozone generation control channels that energize at least four independent ozone generation plates. The at least four independent ozone generation control channels allow for multiple modes of operation, including sterilization, disinfecting, and managing, in addition to interleaved operation, which significantly extends the useful life of the individual ozone generation plates. The ozone generator is placed in a preexisting conditioned airflow that enters a conditioned airspace enclosed by a container. Being placed in the preexisting conditioned airflow, the ozone generator does not require a fan or other air movement device to actively transport ozone-enriched air or oxygen through the ozone generator.

An ozone injector device comprising a housing having a water passageway through the housing, an ozone inlet in fluid communication with the water passageway, a corona tube disposed within the housing and in fluid communications with the ozone inlet, and a clearing piston positioned to move into and out of the water passageway towards the ozone inlet, and configured to prevent flow of ozone into the water passageway.

An ozone injector device comprising a housing, a corona tube disposed within the housing and configured to generate ozone, a check-valve having a first end removably coupled to the water passageway and a second end configured to receive ozone, the second end having a cavity with a movable float contained therein, an ozone inlet fitting removably coupled to the second end of the check-valve, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube such that ozone entering the water passageway through the ozone inlet must pass through the check valve, and a spring-loaded clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet, the clearing piston being biased upwards, and configured to prevent flow of ozone into the water passageway.

An ozone generation system which is adaptable for supplying ozone to different medium and small application processes. The system has a source of feed gas, a corona discharge cell receiving the feed gas from the feed gas source and generating ozone for the application process, a flow controller measuring and managing the flow of the feed gas from the feed gas source to the corona discharge cell; and a regulator receiving gas from the corona discharge cell and sending the gas to the application process. The regulator maintains pressure in the corona discharge cell independent of the application process pressure.

An ozone generator includes a first end plate, a second end plate located opposite the first end plate, a metallic electrode held at both ends by the first and second end plates, a dielectric located inside the metallic electrode with a discharge gap, and including an open end on a first end plate side and a closed end on a second end plate side, a conductive film located on an inner surface of the dielectric, and a high voltage feeding terminal electrically coupled to the conductive film. The conductive film and the high voltage feeding terminal are at least partially in a same position as the first end plate in axial direction of the dielectric. An end of the conductive film and an end of the high voltage feeding terminal on a dielectric opening side extend further toward the opening of the dielectric than the first end plate in the axial direction.

An automatic optimization of an ozone generating device with a control PC board that controls a corona discharge cell via a microprocessor. An alarm, conveyed through a diagnostic LED, show how the cell is performing. The microprocessor is programmed to monitor current draw, transformer input voltage and length of time of use of the corona discharge cell. LED diagnostic indicator lights give a twelve function diagnostic ability including showing if the generating device is turned off; if the generating device is powered but the pilot input is off; the time between when the pilot input is supplied with voltage and the high voltage finally turns on; the high voltage output is on and stable; the auxiliary output signal lines normally closed or normally open are shorted; the programmed maintenance time has expired.

A sterilization case can be reduced, and it is possible to reliably sterilize not only the surface of a mobile communication device but hidden portions thereof as well. A sterilization case includes a case main body and a cover body. The case main body includes a voltage supplying part and a loading part having an electrode sheet. The voltage supplying part includes a boosting circuit, a direct-current conversion circuit, a switch circuit, and a sterilization meter. The boosting circuit supplies the voltage necessary to generate ozone to the electrode sheet. The direct-current conversion circuit performs conversion to a power source voltage of a smartphone as the mobile communication device and outputs to a male connector. The male connector can be connected to a female connector of the smartphone. The cover body is attached to the case main body so as to be able to open and close.

A method is disclosed for balancing loss energy distribution in a drive circuit which drives a resonant load. The method includes the steps of using a plurality of switches to modulate a flow of electrical energy to a resonant load, and providing each of the plurality of switches with a diode connected in anti-parallel to its respective switch. The method further includes generating a voltage-modulated waveform across the resonant load which results in a first amount of loss energy distributed equally among the plurality of switches, and a second amount of loss energy distributed equally among the diodes.
