CAPACITOR PRE-CHARGE CIRCUIT, MOTOR DRIVE SYSTEM, ELECTRIC-POWERED POWER STEERING SYSTEM, AND AIRBAG SYSTEM |
| 摘要 |
<p>The purpose of the present invention is to reduce loss (heat generation) in a capacitor pre-charge circuit and to make the circuit more compact. A capacitor pre-charge circuit according to the present invention charges a capacitor to be charged while inhibiting the voltage at both ends of the capacitor from rising, by dividing the voltage of a power supply using a switched capacitor voltage-dividing circuit (refer to Fig. 1).</p> |
