description The utility model discloses a fault detection system for a charge-discharge circuit, and a synchronization pulse signal is connected with the input end of a controller. A reference signal and a sampling signal are connected with a comparison circuit at the same time. The comparison circuit is connected with the controller through a triggering circuit. The comparison circuit is connected with a fault processing device through a logic processing circuit. The controller is connected with the fault processing device through the logic processing circuit. The system employs a simple circuit and achieves the detection of two faults of the non-operating of a trigger switch and the short circuit of a charging load, and greatly simplifies a conventional method. The system is adjustable in sensitivity and is suitable for occasions with different demands. The sensitivity is adjusted through adjusting the target value of a counter, so the system is convenient and reliable. Moreover, the system is lower in cost.
