  • Patent number: 9906118
    Abstract: A system for performing ozone water treatment comprises a voltage supply circuit and a plasma eductor reactor. The voltage supply circuit includes an H-bridge controller and driver, a transformer, and an output port. The H-bridge controller and driver are configured to switch the electrical polarity of a pair of terminals. A primary of the transformer is connected to the H-bridge driver and controller. A secondary of the transformer connects in parallel with a first capacitor and in series with an inductor and a second capacitor. The output port connects in parallel with the second capacitor. The plasma eductor reactor includes an electric field generator, a flow spreader, and a diffuser. The electric field generator includes a pair of electrodes that generate an electric field. The flow spreader supplies a stream of oxygen. The diffuser supplies a stream of water. The streams of water and oxygen pass through the electric field.

  • Publication number: 20050110038
    Abstract: A high voltage semiconductor device, having a first layer of semiconductor material, a current localization region, a second layer of semiconductor material and a third layer of semiconductor material, is utilized to improve the electrical characteristics of the device by reducing the thickness of the second layer. The reduction of the thickness of the second layer provides for a reduction in edge failures as compared to prior art. The reduced thickness of the second layer also provides for a reduction in forward voltage drop across the device. The reduced thickness of the second layer also results in a reduced dynamic impedance of the device.
