Abstract:
A power conversion control device for electric vehicles that is small and inexpensive and has a low current consumption is obtained. Respective insulated power supplies (6a) to (6f) that form pairs are connected to gate drive circuits (5a) to (5f). A low-voltage side of an insulated communication circuit (8) is supplied, from a low-voltage battery (1), with power that has been stabilized to a constant voltage via a constant-voltage circuit (3). A high-voltage side of the insulated communication circuit (8) is operated with the insulated power supply (6f) that is at least one insulated power supply of the insulated power supplies (6a) to (6f) to insulate and transmit a voltage signal of a high-voltage battery (2) from the high-voltage side to the low-voltage side.
