摘要： PROBLEM TO BE SOLVED: To reduce the loss of voltage-drive semiconductor switching elements including an IGBT without making a device complex. SOLUTION: A power source voltage Vgs of a gate drive circuit 231 is made controllable by a command from a voltage command device (a microcomputer) 234, and is changed according to data including the temperature of the elements and a DC-side voltage Vp of an inverter to adjust the gate voltage Vg of the IGBT 211. For instance, when the temperature of cooling water of the elements is low enough to have a margin thermally, the gate voltage is set low to reduce noises. Conversely, when the DC-side voltage Vp of the inverter 21 is high, the gate voltage Vg is raised to reduce the switching loss of the IGBT. COPYRIGHT: (C)2007,JPO&INPIT
