Title:
SOLENOID DRIVING CIRCUIT
Document Type and Number:
Japanese Patent JP2021082752
Kind Code:
A
Abstract:
To provide a solenoid driving circuit that can increase power discharged from capacitive means that drives the solenoid when energized by increasing the back electromotive force stored in the capacitive means.SOLUTION: In a solenoid driving circuit, first switch means 2, a solenoid 3, and a second switch means 4 are connected in series. A first rectifier diode 5 is connected in parallel with the solenoid 3 and the second switch means 4. A second rectifier diode 6 is connected in parallel with the first switch means 2 and the solenoid 3. Capacitance means 7 for storing power is connected in parallel with the first switch means 2, the solenoid 3, and the second switch means 4. A third rectifying diode 8 is connected in series between the positive side of a power supply 1 and the capacitance means 7 on the positive side of the power supply 1 from a connection point between the capacitance means 7 and the first switch means 2.SELECTED DRAWING: Figure 1
