CONTROL APPARATUS FOR RELAY AND CONTROLLING METHOD THEREOF |
摘要 |
A control apparatus for a relay and controlling method thereof. The controlling method includes: detecting an input voltage of the relay and a current flowing through the relay; obtaining a voltage zero crossing point information according to the input voltage and a reference voltage value; turning on the relay at an initial turn-on time point according to the voltage zero crossing point information, and obtaining a real turn-on time point of the relay according to the current flowing through the relay; obtaining a turn-on delay of the relay according to the initial turn-on time point and the real turn-on time point, and adjusting the initial turn-on time point to obtain a compensated turn-on time point according to the turn-on delay. |
