Problems solved by technology

If the power is off, the discharge resistor provides a discharge path for the filter capacitor to discharge. However, if the circuit is in normal operation and becomes a standby operation, the discharge resistor will consume extra power, resulting in energy waste.
[0004] This shows that above-mentioned existing discharge resistor obviously still has inconvenience and defective, and needs to be further improved
In order to solve the above problems, related fields have tried their best to find a solution, but no applicable method has been developed for a long time.

Abstract

The invention discloses a power supply device and a method for controlling the electric quantity of a capacitance assembly. The power supply device comprises at least one capacitance assembly, an electronic switch and a control device, wherein the capacitance assembly can be arranged in an electromagnetic interference filter and is electrically coupled with an alternating-current power supply. When the power supply device is used, the electronic switch can be started by the control device to release the electric quantity of the capacitance assembly when the alternating-current power supply is cut off.

Description

technical field [0001] The present invention relates to electrical technology, and in particular to a power supply device. Background technique [0002] In recent years, due to the development of industry and commerce and the progress of society, the relatively provided products are mainly aimed at convenience, reliability, and economic benefits. Therefore, the products currently developed are more advanced than before, and can contribute to society. [0003] In the design of the power circuit, the filter capacitor is often connected in parallel with a discharge resistor. When the power is off, the discharge resistor provides a discharge path for the filter capacitor to discharge. However, if the circuit is in normal operation and becomes a standby operation, the discharge resistor will consume extra power, resulting in energy waste. [0004] It can be seen that the above-mentioned existing discharge resistor obviously still has inconvenience and defects, and needs to be fu...
