Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] A power supply module with programmable output of the present invention, such as figure 1 As shown, it includes a control unit, a main power supply circuit, a battery power supply circuit, and a DC power supply. The control unit is connected to the main power supply circuit, the battery power supply circuit, and the DC power supply respectively, and the DC power supply is connected to the main power supply circuit and the battery power supply circuit respectively. The DC power supply is used to provide output energy to the main power supply circuit and the battery power supply circuit.

[0024] The DC power supply is used to convert a fixed value of DC input voltage into a target value of DC output voltage. The target value is given by the control circuit, and an accurate output is obtained after feedback. The main power supply circuit is used to prov...

Abstract

The invention discloses a programmable output power supply module, which comprises a control unit, a main power supply circuit, a battery power supply circuit, and a DC power supply. The control unit is respectively connected to the main power supply circuit, the battery power supply circuit, and the DC power supply. circuit, battery power circuit connection. The DC power supply is used to provide output energy to the main power supply circuit and the battery power supply circuit. The battery power supply includes a voltage follower as the output and input follower of the battery power supply. In this application, the digital set value is output, and then the analog output feedback is collected to realize high-precision closed-loop control, improve the output accuracy, reduce the cost, and reduce the volume.

Description

technical field [0001] The invention relates to the technical field of battery modules, in particular to a programmable output power supply module. Background technique [0002] At present, the market is full of common 3C products, such as smart boxes, mobile phones, PADs, electronic scales, etc., all need to provide power to the products and test their current. Those with lithium batteries also need to test the charging function of the products. The current industry practice is to use a standard battery simulator (instrument) to receive instructions from a PC to output the required voltage and current. However, this kind of battery simulator has the problems of high cost, long delivery period, large volume, and inconvenient equipment miniaturization. How to design a low-cost, small-volume, and portable power module is an urgent problem to be solved at present. Contents of the invention [0003] The purpose of the present invention is to provide a programmable output pow...
