Embodiment 1

[0055] Please refer to the attached Figure 1-17 , a high-efficiency smart charger of the present invention, a high-efficiency smart charger, the smart charger 100 includes a casing and a plurality of USB charging sockets arranged on the casing, and also includes a single-port high-speed smart fast charging socket, A charging port identification chip compatible with smart mobile terminal equipment is provided on the circuit board in the housing;

[0056] The circuit board is provided with a main control circuit, a protocol conversion circuit 200, an output voltage regulation circuit 300, and a Type C socket compatible PD protocol circuit 400;

[0057] The main control circuit includes:

[0058] The PWM pulse width modulation microprocessor used to improve the output efficiency during low voltage and high current and the synchronous rectification circuit connected with the PWM pulse width modulation microprocessor circuit; the PWM pulse width modulation microprocessor circuit ...

Embodiment 2

[0080] A conversion method of a high-efficiency smart charger conversion protocol, characterized in that the conversion method includes the following methods:

[0081]1) After decoding according to the pulse width from left to right through the BMC, a series of disordered combinations of 01 are obtained;

[0082] 2) By observing the combination of 01, it can be seen that there are 64 pairs of 01 preambles from the left, which are used as data waiting and interference removal;

[0083] 3) After the 64 pairs of preambles are decoded by BMC, the data of the preambles are removed, which is not the final data that can be parsed;

[0084] 4) The PD communication protocol adds a soft code for 4B5B code;

[0085] 5) Every 5 binary data of the data received by the PD communication protocol needs to be restored to the correct PD communication data through a 4B5B encoding table;

[0086] 6) After taking out the boot code, the obtained data is 00011 00011 00011 10001 10010, and the fina...

Description

technical field [0001] The invention relates to a charger, in particular to a high-efficiency intelligent charger and a conversion method of the charger conversion protocol. Background technique [0002] As the functions of market products continue to increase, the interfaces of commonly used mobile phones and notebooks change. People travel with several chargers to charge different interface devices and different types of mobile phones. At the same time, the battery capacity is also increasing. For people who spend too much time waiting for the charging time of the product, this charging method is very inconvenient, so it is necessary to solve the charging time and a charger compatible with multi-interface and multi-protocol mobile phones. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a high-efficiency smart charger and a conversion method of the charger conversion ...
