摘要： PROBLEM TO BE SOLVED: To perform switching control by avoiding the influence of the rotation of a motor 200 and knowing the offset amount to avoid the detection error of an inverter current idc even when the motor 200 rotates. SOLUTION: When the motor 200 rotates due to external factors such as the fact that a fan mounted on the motor 200 receives wind, induced voltage is generated on the motor 200. This causes the unintended inverter current idc to be flown when a smoothing capacitor 31 is charged. During charging the smoothing capacitor, the offset of the inverter current idc is not correctly known. Accordingly the offset of the inverter current idc is obtained after finishing charging. Switching signals T1 to T6 control an inverter 1 based on the offset to drive the motor 200. COPYRIGHT: (C)2008,JPO&INPIT
