How to discharge an integrated power supply

There are three methods to safely discharge the capacitors of the PSU. Don't bet your life on it though! I've zapped myself with 400 V DC off the PFC stage once. A prototype board made by yours truly. In spite of all the care we engineers take, it is nearly impossible to eliminate static electricity completely. Semiconductor manufacturers add chip protection to make their devices more resistant to stray. As supporting elements in electrical/electronic/programmable electronic (E/E/PE) safety-related systems, power supply blocks are critical to the transition such systems into a safe state. By improving the robustness and systematic capability of these blocks, related systematic failures are. ...
