Certainly, the basic schematic for a wireless charging receiver involves a few key components: an antenna coil (often referred to as the "receiving coil"), a rectifying circuit typically made up of diodes to convert AC to DC, and a filtering capacitor to stabilize the output voltage. There may be an additional circuit for voltage regulation, depending on the specific power requirements of the device being charged.
Here's a simplified outline for a basic wireless charging receiver:
  1. Receiving Coil (L1): This coil captures the electromagnetic fields from the charging pad's transmission coil.
  2. Rectifier (D1, D2, D3, D4): This converts the alternating current (AC) picked up by the coil into direct current (DC). A common choice here is a full-wave rectifier.
  3. Filter Capacitor (C1): This capacitor smooths out the DC signal, reducing ripple to provide a steady DC output.
  4. Voltage Regulator (U1): If your application requires a specific voltage, a voltage regulator ensures a consistent output irrespective of input fluctuations.
Schematic Connections
  • Receiving Coil (L1): The ends of the coil connect to the input of the rectifier circuit.
    • Connect L1:1 to D1:anode and D4:cathode.
    • Connect L1:2 to D2:anode and D3:cathode.
  • Rectifier (Full-wave): From L1 to the diodes.
    • Connect D1:cathode to D2:cathode, and also connect this point to the positive terminal of C1.
    • Connect D3:anode to D4:anode, and also connect this point to the negative terminal of C1.
  • Filter Capacitor (C1): Placed across the DC output of the rectifier to reduce ripple.
    • Connect C1:1 (positive) to the positive voltage output.
    • Connect C1:2 (negative) to the ground.
  • Voltage Regulator (U1): If needed, this is connected after the capacitor to ensure a stable output voltage.
    • Connect U1:input to C1:1.
    • Connect U1:ground to C1:2.
    • U1:output provides the regulated voltage for your device.
Assumptions made:
  • The receiving coil is tuned to the frequency of the transmitting coil for optimal energy transfer.
  • A full-wave rectifier is chosen for efficiency but you could also use a half-wave rectifier for simplicity.
  • The voltage regulator is optional and chosen based on the required output voltage for your device.
Please adjust component values such as the inductance of L1, the capacitance of C1, and the specifics of the voltage regulator U1 according to the power requirements and operating frequency of your wireless charging application. Also, it would be best to place the receiving coil (L1) as close as possible to the transmitter coil without any metal objects in between to avoid interference and energy loss.
