Self-controlled multi-voltage output system for standby power

Abstract

The invention discloses a self-control multi-voltage output system of a reserve power supply. The self-control multi-voltage output system of the reserve power supply comprises an electric supply charging unit, a solar energy charging unit, a storage battery pack, a charging and discharging protective module and a power output unit. The electric supply charging unit and the solar energy charging unit charge the storage battery pack through the charging and discharging protective unit in an alternative mode, and the output end of the charging and discharging protective unit is connected with the input end of the power output unit and conducts discharging management on electric energy of the storage battery pack. The power output unit comprises a first direct-current power output circuit, a second direct-current power output circuit, a third direct-current power output circuit and an alternating-current power output circuit, wherein the first direct-current power output circuit is used for outputting a 5V-to-36V direct-current voltage, the second direct-current power output circuit is used for outputting a 4V-to-6V direct-current voltage, the third direct-current power output circuit is used for outputting a 10V-to-14V direct-current voltage, and the alternating-current power output circuit is used for outputting an AC220V / 50Hz alternating-current voltage. The self-control multi-voltage output system of the reserve power supply has a solar energy charging function and an electric supply charging function, can achieve a multi-voltage output function and integrate a plurality of types of common voltages, and is convenient to carry.

Description

technical field [0001] The invention relates to power supply equipment, more specifically, to a self-controlling multi-voltage output system of a standby power supply. Background technique [0002] With more and more applications of consumer electronic products in people's daily life, such as: notebook computers, MP3, MP4, mobile phones, digital cameras, etc., these consumer electronic products have become an indispensable part of people's lives. With the increasing number of consumer electronic products, there will be a problem. Most of the consumer electronic products in the prior art are powered by lithium batteries. A sudden power outage. Although various electronic products are generally equipped with a charger, because the voltage required by each electronic product is different, and the power interface of various electronic products is also different, so there is no way to make the charger universal. When carrying multiple electronic products on business trips or to...

AI Technical Summary

Problems solved by technology

Although all kinds of electronic products are generally equipped with a charger, because the voltage required by each electronic product is different, and the power interface of various electronic products is also different, so there is no way to make the charger universal. When carrying multiple electronic products on business trips or tourism, it is necessary to carry multiple chargers at the same time, causing a lot of inconvenience

At the same time, the current chargers for consumer electronic products only have the function of voltage conversion and charging, and they are powerless without an external power supply.
