Mobile phone charger based on thermoelectric power generation

Abstract

The invention discloses a mobile phone charger based on thermoelectric power generation. The mobile phone charger comprises a thermoelectric power generation module, a boosting module, a driving module, an isolation rectifying circuit and an isolation sampling module, wherein the thermoelectric power generation module utilizes a plurality of serially connected or parallelly connected thermoelectric power generation sheets to generate one low voltage under the condition of a certain temperature difference; the boosting module is connected with the output end of the thermoelectric power generation module to enable the low voltage to be boosted to a high voltage; the driving module is connected with the output end of the boosting module so as to enable the high voltage output by the boosting module to be converted into stable alternating current to be output; the isolation rectifying circuit is connected with the output end of the driving module so as to perform isolation rectification on alternating current output of the driving module to generate stable output to be output through an output interface; the isolation sampling module feeds the output back to the driving module to perform dynamic regulation so as to stabilize the voltage after sampling isolation is performed on the output of the isolation rectifying circuit. The mobile phone charger based on the thermoelectric power generation utilizes the thermoelectric power generation principle, adopts reasonable heat-conduction and heat-dissipation devices and boosting and voltage-stabilizing circuits, achieves the purpose of mobile phone charging, and is particularly suitable for outdoors and field emergent service.

Description

technical field [0001] The invention relates to a mobile phone charger, in particular to a mobile phone charger based on temperature difference power generation. Background technique [0002] Common emergency mobile phone chargers include lithium battery type, solar type, etc. The built-in lithium battery type builds the lithium battery in the device, without installing a battery, and can directly supply power to the device. Generally, it is 800mAh---2000mAh. This type of product is generally characterized by small size, portability and convenience. At present, this kind of equipment is widely used. Applied in charging various digital products. The solar charger converts solar panels into electric energy and stores them in the battery. The battery is any form of power storage device, mainly lead-acid batteries. The load is not only digital products such as mobile phones. The load is diverse. A variety of electronic digital products supplement the power supply, and the prod...

AI Technical Summary

Problems solved by technology

[0003] For the emergency mobile phone chargers in the prior art, there are problems such as unstable power supply and poor continuity in the charging methods.

Lithium batteries or ordinary dry batteries have the problem of one-time consumption as a backup power source. Carrying a large amount of disposable power sources during outdoor and field activities will undoubtedly increase the burden.

The solar energy type has higher requirements on the external environment, and cannot be taken and used at any time, and cannot meet the emergency requirements

Some other emergency charging methods have problems such as poor stability, difficulty in continuous use, and certain hazards to equipment
