PROBLEM TO BE SOLVED: To provide a serial-parallel mixture conversion drive system, in which the rotating speed, torque and output of each motor are continuously controlled in a serial-parallel mixed state from serial to parallel. SOLUTION: A serial circuit made up of a forward diode CR100 and a switch element S101 connected serially between DC electric drivers EMD10 and EMD102, a serial circuit consisting of a switch element S112 and a reverse direction diode CR102, and a serial circuit made up of reverse direction diode CR101 and a switching element S111 are all connected in parallel to a power supply DCV100. In addition, a point between the switch element S101 and the DC electric driver EMD102 is connected to a point between the switching element S112 and the diode CR102, while a point between the DC electric driver EMD101 and the diode CR100 is connected to a point between the diode CR101 and the switching element S111. |
