6 FAQs about [Power supply charges the capacitor voltage]

How does a power supply charge a capacitor?

The charging mode ends when the capacitor voltage equals the output voltage of the power supply. The capacitor is continually refreshed by the power supply. During the discharge mode, the charging resistor isolates the power supply from the pulse load. The advantages of this technique are its simplicity, reliability, and low cost. FIGURE 21.3.

How does a capacitive power supply work?

A capacitive power supply usually has a rectifier and filter to generate a direct current from the reduced alternating voltage. Such a supply comprises a capacitor, C1 whose reactance limits the current flowing through the rectifier bridge D1. A resistor, R1, connected in series with it protects against voltage spikes during switching operations.

How does a DC power supply work?

Conventional dc power supplies operate at a given dc output voltage into a constant or near constant load. Recharging the capacitor voltage to a specified voltage is tasked to a capacitor charging power supply (CCPS). The charging mode ends when the capacitor voltage equals the output voltage of the power supply.

Why does a capacitor not discharge back into a power supply?

What is not shown is that the input must contain a diode or similar component, so if the input voltage is lower than the capacitor plate voltage then the capacitor does not discharge back into the power supply. (I'm 20 years past A-levels and still find the marking schemes obtuse, they're simplified beyond the point of understanding)

How are energy storage capacitors charged?

Energy storage capacitors may be charged utilizing the same power electronic technology that has been applied in switching converters for constant power loads. Instead of charging the energy storage capacitor with a single pulse, switching converters can charge the capacitor with a series of pulses or pulse train.

Why do I need a capacitor for a bridged audio power amp?
