If you don't know what is the topology and how it failed you should not assume it is safe to put your greasy noob fingers in it.
- bsder 6y agoYou will note that my calculations assume that the caps are charged to the high-side voltages ... And I'm really, really struggling to come up with a switch-mode power supply topology design that has more than 100uF anywhere. I stand by my statement. The biggest problem when dealing with power supplies nowadays is getting the shit shocked out of you when they're plugged in--especially if you don't realize it.
