AI Technical Summary
The reverse connection protection circuit of the existing motor controller uses an uncontrollable diode, resulting in poor reliability and inability to achieve rapid power-down.
The system employs a reverse connection protection circuit and a wake-up circuit. The reverse connection protection circuit includes a first switch and a second switch connected in series. The wake-up circuit controls the switching on and off of the switch by receiving a power-on wake-up signal, a network wake-up signal, and a power supply signal from the downstream stage, thereby achieving controllable power supply and rapid power-off of the low-voltage power supply.
The reliability of the power supply circuit of the motor controller has been improved, enabling rapid power-on and power-off control of the subsequent circuits, reducing dark current, and ensuring circuit stability and electromagnetic compatibility.
