Description

A kind of QC4.0 intelligent recognition fast charge charge power supply battery charge controller

Technical field

The utility model relates to light source of charger technical field, specifically a kind of QC4.0 intelligent recognition fast charge charge power supply Battery charge controller.

Background technique

With popularizing for various electronic products, especially mobile phone type and tablet computer, laptop is more and more extensive, hand Requirement of the machine to charger is also higher and higher, and the mobile phone or computer of different brands are also different required by the output voltage to charger Sample, some 5V, some 9V, some 12V ... or even same portion's mobile phone, in different electricity, charging voltage can be different. So to meet various mobile phone, at present for regular tap mains charger, market demands are unable to reach in design, greatly Charger voltage of the part with USB only exports 5V, and electric current is unable to reach higher voltage and bigger electricity within 2.4A Stream.

Utility model content

The purpose of this utility model is to provide a kind of QC4.0 intelligent recognition fast charge charge power supply battery charge controller, with Solve the problems mentioned above in the background art.

To achieve the above object, the utility model provides the following technical solutions:

A kind of QC4.0 intelligent recognition fast charge charge power supply battery charge controller, comprising: lightning protection module, EMI inhibit mould Block, rectification filtering module, primary transform circuit module, secondary commutation voltage reduction module, intelligent measurement identification module, PWM control module, Voltage Feedback control module and intelligent measurement pressure stabilizing control module, alternating current input passes sequentially through lightning protection module, EMI inhibits mould Intelligent measurement identification module is connected after block, rectification filtering module, primary transform circuit module and secondary commutation voltage reduction module.

As a preferred embodiment of the present invention: the intelligent measurement identification module is also connected with DC output, the model of DC output Enclosing is 3.3V-20VDC.

As a preferred embodiment of the present invention: the intelligent measurement identification module is also connected with intelligent measurement pressure stabilizing control mould Block, intelligent measurement pressure stabilizing control module are also connected with Voltage Feedback control module, and Voltage Feedback control module is also connected with PWM control mould Block, PWM control module are also connected with primary transform circuit module.

As a preferred embodiment of the present invention: the rectification filtering module is also connected with PWM control module.

As a preferred embodiment of the present invention: the voltage protection module includes fuse, varistor and temperature-sensitive electricity Resistance.

Compared with prior art, the utility model has the beneficial effects that the utility model is more suitable for using voltage to more Equipment power supply, shortens the charging time, and the basic exclusion past one matches one charge function.It is useful to realize a charger completion institute Electric equipment charge requirement.The cumbersome of a variety of chargers is carried before solving, brought to user's use be more simply more convenient it is faster. And output voltage is the agreement according to electrical equipment, and intelligent recognition reaches current desired voltage, range: 3.3V-20VDC, And electric current maximum can reach 5A.It charged for a long time 80% or more the time of minimum shortening for the past.
