Wireless power transmission with modular output

Mobile side circuitry of a wireless power transmission system, comprising:

• a mobile side resonant circuit adapted to inductively couple the mobile side circuitry to a stationary side circuitry of the wireless power transmission system;
• a mobile side rectifier stage adapted to rectify an input signal for supply of power to a mobile side load;
• and
• a mobile side transformer stage directly connected at its input side to the mobile side resonant circuit and connected at its output side to the mobile side rectifier stage;
• wherein
• the mobile side transformer stage comprises a same number n>1 of primary side windings and secondary side windings;
• the mobile side rectifier stage comprises one mobile side AC/DC converter connected to each secondary side winding;
• wherein
• the mobile side AC/DC converters are realized as synchronous rectifier circuits which are controlled according to a DC output current being measured indirectly through measurement of an input side current of the mobile side rectifier stage;
• and
• output terminal pairs of the plurality of mobile side AC/DC converters are connected in series or output terminal pairs of the plurality of mobile side AC/DC converters are connected in parallel or mobile side AC/DC converters are grouped into a plurality of mobile side output groups such that output terminal pairs within each mobile side output group are connected in series and output terminal pairs of different mobile side output groups are connected in parallel.
