CAPACITOR PRECHARGE CIRCUIT, MOTOR DRIVE SYSTEM, ELECTRICALLY POWER STEERING SYSTEM, AND AIR BAG SYSTEM |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To reduce the loss (heat generation) in a capacitor precharge circuit and reduce the size of the circuit. <P>SOLUTION: A capacitor precharge circuit according to this invention divides the power source voltage by using a switched capacitor voltage dividing circuit and thereby charging a capacitor while suppressing the voltage across the capacitor that is charged. <P>COPYRIGHT: (C)2013,JPO&INPIT |
