Splet14. okt. 2016 · Conducted EMI of switching power converters contain both common-mode (CM) and differential-mode (DM) components as illustrated in Figure 1. The high slew rate of the switching node generates CM noise in a switching power converter and couples the noise through the transformer’s inter-winding capacitance, Cps to earth ground. Splet22. apr. 2014 · Here is a short tutorial on how to discharge the capacitors in a power supply so you can safely repair it: Do not short the terminals of a filter capacitor with a screwdriver. This can be dangerous. Screw a 100-watt lightbulb into a socket with exposed leads. Attach one lead to each terminal of the capacitor, the bulb should illuminate.
SpletWith higher voltage, you can produce more power. The main 'rail voltage' generated by power supplies in class AB car audio amplifiers is generally between ±30v and ±50v. In large class D amplifiers, the voltage can be greater than ±150v (I've measured more than 300v across the rails in some amps).
