Power grid is polluted, therefore front stage circuits need to have soft power on and power factor emendation function.
It is retrieved, there is following several frequently seen wireless power transmission front stage circuits design scheme:

Electricity, still, the circuit power on that rush of current is big, and DC voltage is non-adjustable, and can not achieve PFC.
Second: using BOOST type circuit of power factor correction (Power Factor Corrector, PFC), such as paper
" Design and Experimentation of WPT Charger for Electric City Car " takes such open up
It flutters, since series connection can ensure that input side has electric current in entire cycle, which can be realized unity power factor,
But the circuit can not achieve it is soft power on, and DC output voltage only has boost capability.
Third: BUCK type circuit of power factor correction, since BUCK circuit requirement input voltage is higher than output voltage,
The circuit cannot work normally in whole wave, therefore input current will appear cutout situation, cause power factor poor.
By retrieval, also it is not disclosed at present while there is stepping functions, power factor emendation function and soft upper electric work
It can front stage circuits.
