摘要： AC to DC power electronic converter circuitry includes isolated converter circuitry and control circuitry coupled to the isolated converter circuitry. The isolated converter circuitry includes one or more wide bandgap switching components. The control circuitry is configured to drive at least one of the wide bandgap switching components such that the power electronic converter circuitry is configured to generate a DC output with an output power greater than 100W at an efficiency greater than 92%. Using wide bandgap components in the isolated converter circuitry allows the power electronic converter circuitry to achieve a high efficiency and high power density.

摘要： Disclosed is a DC-DC converter with a converter bridge, tank circuitry, and rectifier circuitry. In one embodiment, the converter bridge includes multiple switch circuits, which are formed with silicon carbide MOSFETs (metal on semiconductor field effect transistors), and are configured to provide a primary current. The tank circuitry includes a resonant capacitance, a resonant inductance, and a transformer with a primary, a first secondary, and a second secondary. The tank circuitry is configured to receive the primary current, and the transformer is associated with a magnetizing inductance. The resonant frequency of the tank circuitry is greater than about 225 kilohertz as essentially defined by the magnetizing inductance, the resonant capacitance, and the resonant inductance. The rectifier circuitry is coupled to the first secondary and the second secondary coil, and is adapted to provide a rectified output current.

摘要： A power conversion apparatus and individual components thereof is described. In general, the power conversion apparatus converts a DC output received from an appropriate source, such as string of solar panels, to an AC output. The AC output may be a single-phase or three-phase, sinusoidal AC signal. The inverter system may include a boost converter, which is a DC-to-DC converter, and an inverter, which is essentially a DC-AC converter. In operation, the boost converter will boost the DC output from the appropriate source to a desired DC output voltage. The inverter will convert the DC output voltage to a desired single-phase or three-phase output voltage at a desired frequency, such as 50 or 60 hertz. The boost converter and the inverter may be packaged together in an appropriate sealed and weatherproof housing.
