<P>PROBLEM TO BE SOLVED: To provide a motor drive device including an inverter which controls a direct-current voltage with improved control precision. <P>SOLUTION: There is provided a variable magnetic memory motor drive device 1. In order to boost an input voltage Vdc of an inverter 4 so as to let a magnetization current which magnetizes a variable magnet of a variable magnetic memory motor 2 flow, the variable magnetic memory motor drive device 1 boosts the input voltage Vdc by causing a current interrupting circuit 7 to interrupt a current which flows through a direct-current power supply 5 from a smooth capacitor 6, causes the current interrupting circuit 7 to discharge the smooth capacitor 6, and controls the input voltage Vdc such that the input voltage Vdc becomes a direct-current voltage target value VdcT. <P>COPYRIGHT: (C)2013,JPO&INPIT |
