Modulated voltage for a solenoid valve |
摘要 |
A circuit for actuating an ABS solenoid valve coil with a pulse width modulated voltage having a constant frequency and variable duty cycle. The coil current is a function of the duty cycle of the pulse width modulated voltage. By controlling the duty cycle, current saturation of the coil can be avoided to provide for a faster response upon deactuation of the coil. Feedback is included in the circuit to verify correct functioning of electrical components.
