1, in the Qi standard, there is a fixed frequency voltage regulation mode of work. That is, the fixed operating frequency, according to the dynamic load power requirements, through the voltage regulator unit, to achieve dynamic power output. However, there are availableThe voltage regulator first fixed the working frequency of the voltage regulator unit itself, and then adjusted the input duty ratio to achieve the adjustment of the output voltage. The inherent disadvantages of this method are: 1) When the input voltage changes, it will directly affect the output stage.
2, fixed frequency is better. The working principle of the frequency conversion architecture is to adjust the transmission power by changing the operating frequency, which will cause certain interference to the mobile phone circuit in some transmission bands, and the fixed frequency does not appear this problem.
3, in addition to these third-party brands, there are some transmitters that support Apple 5W as a representative, using a fixed-frequency voltage regulation architecture.Wireless fast charge.

1, should be a sine wave. The receiving side needs resonance. Otherwise the efficiency may be too low.
2, polarity recognition circuit. This is partly caused byR12 and LEDl (TEST red polarity indicator). The protection circuit is composed of Q3 and R7 and other components. Let's say the battery's polarity is reversed. LED1 will light up, warning should switch the switch K, in order to charge normally.
