Abstract

The invention relates to a power supply, especially to an uninterrupted rechargeable battery power supply. The uninterrupted rechargeable battery power supply includes an alternating-current charging power supply, a first rechargeable battery and a second rechargeable battery. The input end of the alternating-current charging power supply is electrically connected with an alternating-current power supply. Two sets of switches (K1, K2) of one set of relay at the positive and negative output ends of the alternating-current charging power supply are connected in series to the positive and negative power supply ends of the first rechargeable battery. Two sets of switches (K3, K4) of another set of relay at the positive and negative output ends of the alternating-current charging power supply are connected in series to the positive and negative power supply ends of the second rechargeable battery. The positive and negative power supply ends of the first rechargeable battery are connected in series in a load RL loop through two sets of switches (K7, K8) of one relay, and the positive and negative power supply ends of the second rechargeable battery are connected in series in the load RL loop through two sets of switches (K5, K6) of another relay. The two ends of the load RL are provided with voltage detecting circuits, the output ends of which are electrically connected with an I / O port of a single chip microcomputer.

Description

technical field [0001] The invention relates to a power supply, in particular to an uninterrupted rechargeable battery power supply. Background technique [0002] In many fields such as weak signal amplification or audio amplification, because the power supply is filtered by the AC 220 through the transformer and rectifier circuit, and then supplied to the system voltage through the voltage stabilization circuit, there is always power frequency interference in the signal, which affects the system. quality. [0003] Although there is very little high-frequency interference for switching power supplies, the large-scale high-frequency interference increases. For this reason, some system preamplifiers are powered by batteries to eliminate the interference signals of these systems. However, there is a common ground phenomenon, and the complete elimination of these effects can only be done through optical isolation amplifiers. It increases system cost and complicates system desi...
