How the energy storage converter is short-circuit protected？

Current Detection

• Function: Monitor the input and output currents of the converter in real time.

• Principle: Use current sensors (such as Hall effect sensors, shunts, etc.) to detect the current. When a sudden increase in the current is detected and it exceeds the preset threshold, the system will determine that a short circuit may have occurred.

Overcurrent Protection

• Function: Quickly cut off the power supply when an overcurrent is detected to prevent the short circuit from developing further.

• Principle:Hardware Protection: Use hardware devices such as fast fuses, circuit breakers, or MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) to cut off the current.

• Software Protection: Execute the protection logic through a microprocessor or controller to control relays or MOSFETs to cut off the current.

Protection Measures

• Cutting off the Power Supply: Cut off the power supply through relays or MOSFETs to prevent the short-circuit current from continuing to flow.

• Alarm Notification: Issue an alarm through the display screen or indicator lights to remind the user that there is a short-circuit fault in the system.

• Fault Isolation: When a short circuit is detected, isolate the faulty part to prevent the fault from spreading to other parts.
