Abstract: A microgrid comprises a meter adapter for interconnection to the electric grid, facility loads, and renewable energy resources using connectors, bus bars, and switches. Adapter connectors and internal bus bars and can be stressed with excessive heat rise from heat losses that arise from carrying high currents due to constraints in the physical size and airflow restrictions. Exhaust ports and/or vents are arranged to achieve a chimney cooling effect in such conditions to meet stringent UL requirements against resultant heat rise within a meter adapter.

Abstract: A converter performs full-wave rectification on a single-phase voltage, thus outputting a rectified voltage across DC power supply lines. An inverter receives the rectified voltage and then supplies a three-phase AC current to an inductive load. Between the DC power supply lines is connected a charge and discharge circuit. The charge and discharge circuit includes a buffer circuit and a boost circuit. The buffer circuit includes a series connection between a capacitor and a switch. The boost circuit, which may be configured by a boost chopper, includes a switch, a reactor and a diode. The charge and discharge circuit provides and receives part of pulsations of the power input to the converter between the DC power supply lines.
