Title:
電源供給回路、電源供給機器および制御方法
Document Type and Number:
Japanese Patent JP6861283
Kind Code:
B2
Abstract:
Provided are a power supply circuit, a power supply device and a control method. The power supply circuit includes a primary rectifier unit, a modulation unit, a transformer, a secondary rectifier and filtering unit, a current feedback unit, and a control unit. The power supply circuit removes a liquid electrolytic capacitor at a primary side. In the power supply circuit, the liquid electrolytic capacitor at the primary side is removed, such that a volume of the power supply circuit is smaller, and is safe to use. Moreover, the control unit may determine a type of a voltage of input alternating current, and set a current limit value in the current feedback unit according to the type of the voltage of the alternating current, such that it is flexible to use the power supply circuit.
