Tailoring for Your System

1. Outline System Requirements

1a. How much power do you need?

The power requirements determine what resonant capacitors you should select and what input voltage you should use.

Power Level	C	Vin
1-50W	200nF	24V

For higher current at lower input voltages, C can be increased. This is just a general guide, users are encouraged to experiment and find the ideal setup for their application.

The power requirements also impact coil selection, as the coil used must be able to handle the required current.

1b. How much distance do you need?

The distance between coils that is required helps to determine what coil size should be used. The rule of thumb here is that good efficiency (85%+) can be achieved when the distance between coils is less than 50% of the coil radius. A typical system with a 3-8mm gap between coils can use the standard 50mm coils for a good result.

1c. Where will the power go?

I would like to directly charge a battery

To directly charge a battery, in the receiver configurator select Battery Charge from the Regulator Mode dropdown. You can then set your charging parameters in the enabled fields.

I would like to output a constant voltage or current

Bridge the Regulate solder jumper on the receiver and set the required output voltage or current in the receiver configurator.

I can handle a wide output voltage range

If your system is capable of handling a wide voltage range, you may be able to completely bypass the integrated regulation system by bridging the Bypass solder jumper in order to improve efficiency, reduce size and save cost.

2. Setup Hardware

Setup coils, capacitors and power output mode. Connect your power supply and load.

3. Configure
