SWITCHING POWER SUPPLY AND ELECTRONIC CONTROL UNIT |
| 摘要 |
A switching power supply converts an input voltage to a predetermined output voltage by controlling a switching device. The switching power supply includes a controller and a current detector. The controller controls the switching device. The current detector detects electric current flowing through the switching device. The controller starts a forced-OFF action to forcedly turn OFF the switching device when the current detected by the current detector exceeds a predetermined threshold and then ends the forced-OFF action at a start of a predetermined switching period. |
