SOLENOID ASSEMBLY ACTUATION USING RESONANT FREQUENCY CURRENT CONTROLLER CIRCUIT
A latch system includes a releasably secured latch or keeper and a solenoid assembly. The solenoid assembly has a solenoid driver coupled to a power supply, a switching circuit connected with the solenoid driver, and a function generator to selectively adjust a frequency of a pick current output from the power supply and provided to the solenoid driver. The frequency is adjusted until the pick current induces a resulting vibration of said latch system sufficient to free a preloaded latch or keeper. The adjusted frequency may be a target frequency or a range of frequencies. Also included may be a preload sensor. When a preload is sensed, the frequency may be adjusted by the function generator until the pick current induces a resulting vibration of said latch system sufficient to free a preloaded latch or keeper.
