    摘要： A system for optimizing dead time of switches, for example in power converters, using software. The system is first calibrated. The system determines the state that switches should be in. If the switch state needs to be changed, the system determines an optimized dead time which needs to be waited between turning one switch off and a complimentary switch on. The system controls the switches to turn on or off switches and waiting only the duration of the optimized dead time.

    摘要： A power conversion apparatus with modified cooling properties has been disclosed. The apparatus comprises an AC port, at least one DC port, a chassis, at least one power conversion module mounted in said chassis connectable to off-board conductors and said AC and said at least one DC ports, a module heat sink attached to each one of said at least one power conversion module for cooling said module, wherein said off-board inductors are mounted in said chassis together and separate from modules with one or more of an inductor heat sink and cooling fluid circulator for cooling said inductors.

    摘要： The present disclosure provides a bidirectional power converter capable of receiving and delivering AC and DC power from and to multiple ports in accordance to its different embodiments. The AC or DC input receives power and at least two power conversion circuits work with a plurality of switches for connecting provides DC or AC current at multiple ports. The power conversion circuits may be rectifier inverters and have module form that connect to the AC and DC ports via a backplane having multiple connectors. The apparatus may also provide DC to DC conversion using a buck/boost circuit.

    摘要： In one aspect the present disclosure provides a system for charging electric vehicles both AC and DC using only two conductors comprising a cable having two ends one of which is attached to a connector and the other end to a plug and only two charging conductors that extend from one end of the cable to the other and either, one or more switches to receive the current from an AC or DC input and direct it based on a type of the current to an AC or DC output and to stop the current if the corresponding port is not available. The system also has a control mechanism for preventing the delivery of the current to the wrong port of the connector.
