SOLENOID DRIVE DEVICE |
摘要 |
A voltage limiting circuit of a solenoid drive device includes a function to limit the value of a boost voltage generated by a boost voltage power source circuit. The voltage limiting circuit is equipped with a boost voltage comparing unit and a boost voltage discharge unit. The boost voltage comparing unit compares a voltage-divided value of the boost voltage with a reference voltage value, and in the case that the voltage-divided value is higher than the reference voltage value, the boost voltage discharge unit lowers the voltage-divided value to be less than or equal to the reference voltage value. |

1. A solenoid drive device comprising:
a solenoid drive unit configured to drive a solenoid; a boost voltage power source unit configured to generate a boost voltage by boosting a power source voltage supplied to the solenoid drive unit; a regenerating unit configured to regenerate in the boost voltage power source unit regenerative energy generated by the solenoid when the solenoid drive unit is turned OFF; and a boost voltage limiting unit configured to limit a value of the boost voltage to be less than or equal to a predetermined voltage value; wherein the boost voltage limiting unit further comprises: a boost voltage comparing unit configured to compare the value of the boost voltage with the predetermined voltage value; and a boost voltage discharge unit configured to reduce the value of the boost voltage, in a case that the boost voltage comparing unit determines that the value of the boost voltage is higher than the predetermined voltage value. |
