Estimating the term…
An electric power converting apparatus mainly includes a first power supply circuit, a second power supply circuit, a selection circuit, a control circuit, a bi-directional inverter circuit, and a charge/discharge circuit. The control circuit composed of a microcomputer or a microprocessor such as a DSP controls an operation of the electric power converting apparatus. The first power supply circuit or the second power supply circuit supplies a operation voltage for the control circuit. The first power supply circuit generates the operation voltage for the control circuit based on an AC voltage supplied from the electric power supply system. The second power supply circuit generates the operation voltage for the control circuit based on a DC voltage supplied from a DC power supply in an electric vehicle EV.
An electric power system for transmission and reception of electric power between an electric power supply system that supplies AC electric power to a load and a vehicle that travels by means of a motor being driven by using electric power charged in a first battery as a drive source,
