Hello,
I'm working on an H-bridge DCDC-DCAC inverter. When I detect a potentially destructive overvoltage or overcurrent, is the proper response always to shut the device off, i.e. stop switching?
Also, I've heard that the threshold can be 150% of nominal assuming your components are rated to far? I this a good rule of thumb? I assume duration would also play a part in choosing whether shut down is needed or not.
Are there standard practices regarding this?
