The failure caused by capacitor damage is the highest in electronic devices, especially with the failure of electrolytic capacitors being the most common. Capacitor damage manifests as: reduced capacity, complete loss of capacity, leakage, and short circuit.Capacitors play various roles in circuits, and the faults they cause are also characterized differently: in industrial control circuit … Read more
Leakage Circuit Breaker / The working principle of the leakage circuit breaker is When functioning normally, there is no leakage current passing through the leakage protector except for the working current in the circuit. At this time, the current flowing through the zero-sequence current transformer (detection transformer) is equal in magnitude and opposite in direction, … Read more
In HIL testing, fault injection is a commonly used testing method, typically implemented using fault injection modules to simulate electrical faults, such as short circuits, open circuits, etc. The principle of fault injection is to introduce signal faults between the tested ECU and other parts of the system, such as voltage fluctuations, ground short circuits, … Read more
