APPARATUS AND METHOD OF OPERATING TWO SWITCHES

摘要

The method is for operating two switches connecting respectively a load to power source terminals in response to a switch control signal. The method comprises the steps of a) detecting a signal indicative of current direction through the load to identify one of the switches as active switch; b) if the switch control signal is for opening the active switch, (i) sending an opening gate signal to the active switch and (ii) triggering a predetermined time period; and c) if the switch control signal is for closing the active switch, (iii) sending an opening gate signal to the other switch, (iv) triggering a predetermined time period, and (v) sending a closing gate signal to the active switch when the predetermined time period of the timer associated with the other switch has elapsed. The present invention also concerns an apparatus.
