Over-voltage protection coil control circuit |
摘要 |
An over-voltage protection coil control circuit has at least one coil driving circuit, wherein an over-voltage protection circuit is connected to the at least one coil driver circuit. The at least one coil driver circuit consists of a transistor. The over-voltage protection circuit is composed of a Zener diode connected to a power supply and the at least one coil driver circuit. When the coil generates a high inverse emf (electromotive force) due to the inversion of its polarity, the Zener diode conducts and guides the high voltage inverse emf to the power supply.
