摘要： According to one embodiment, four VVVF main circuit inverters for supplying electric power to drive a permanent-magnet synchronous motor are packaged into one unit. The four VVVF main circuit inverters are configured as a 4-in-1 inverter unit which shares a cooling mechanism for radiating heat generated due to power supply operation for the permanent-magnet synchronous motors to outside. A 2-in-1 semiconductor device package in which two semiconductor elements to convert electric power are packaged into one unit to be able to drive a permanent-magnet synchronous motor is contained in the 4-in-1 inverter unit. Thereby, individual control of inverters and reducing the size of the entire apparatus can be achieved for the electric-vehicle control apparatus.

摘要： According to one embodiment, an apparatus includes a controller which outputs a signal for controlling ON and OFF of a switch which changes over connection between a second input terminal and the output end of a coil. The controller includes an MPPT control unit which follows a maximum power point with a period based on a zero-cross detection signal of a system voltage based on an input signal acquired by subtracting a value obtained by multiplying a droop gain simulating drooping characteristics, a control unit which outputs a direction value in such a manner that a difference between a reference output from the MPPT control unit and the input signal becomes zero, and a PWM comparator which outputs a PWM signal based on the direction value and a triangular wave voltage.
