The P9030 supports all WPC coils (single and multi-coil configurations) that can be driven with a half-bridge inverter,DC-input of 10-20V, and a 110-205kHz switching frequency.  Within these parameters, both WPC as well as proprietary coils may be used.  On the receiver side, we work with all types of coils: WPC recommended (RX-A,B,C,D,E), custom coil modules, PCB based, flexible PCB etc.  Our solution provides a great deal of flexibility to support proprietary solutions, or coils made from different materials, such as PCB based coils in addition to wire wound coils.
