Abstract： |
The circuit contains a single processing circuit, it receives the control pulse. A from the electronic control unit of the motor and output high voltage driving pulse Ah and low voltage driving pulse Al to higher extreme driving circuit separately and receive the feedback sampling current signal from lower extreme driving circuit, after processing, the low voltage driving pulse Al adjust the higher extreme driving circuit to adjust the driving circuit of the electromagnetic valve. Lower extreme driving circuit receive pulse signal B from electronic control unit of the motor, this pulse signal is same with the control signal A. |
