A higher resistance will slow down the discharge process, while a lower resistance will speed it up. Using a discharge tool with a resistor can control the discharge rate. Initial Voltage: The higher the initial voltage across the capacitor, the longer it will take to discharge. Capacitors with higher voltages will take more time to release their stored energy …
In addition to Autistic''s correct answer, the value of C9 (X rated) is a compromise between consuming excessive AC current at 60 Hz while suppressing the noise voltage spikes by about 3 dB to 6 dB at the transformer primary if power is cut off when the 60 Hz sine wave is at or close to peak current. C9 does NOT behave like a MOV or TransZorb, …
For the step-up DC/DC converters, please choose a MOSFET with a rated current two or three times more than the peak current. For the step-down DC/DC converters, a rated current around two times of the output current multiply by step-down ratio should be selected. Please check the current waveform and the heat of the MOSFET by an actual
