Design with wireless power reciever coil in Cirkit DesignerThe Wireless Power Receiver Coil (Manufacturer: DIY, Part ID: Receiver Coil 15 Turns) is a key component in inductive charging systems. It is designed to receive energy wirelessly from a transmitter coil by converting the electromagnetic field into electrical energy. This energy can then be used to power electronic devices or charge batteries.
Wireless power receiver coils are commonly used in applications such as:
This circuit consists of multiple copper coils connected to transmitters and a receiver, likely forming a wireless power transfer or communication system. The transmitters are connected to individual coils, and the receiver is connected to another coil, facilitating the transmission and reception of signals or power wirelessly.

The receiver coil itself does not have traditional "pins" but typically connects to a rectifier circuit via two terminals. Below is a description of the terminals:
| Terminal | Description |
|---|---|
| Terminal 1 | Coil input/output terminal (connects to rectifier) |
| Terminal 2 | Coil input/output terminal (connects to rectifier) |
Note: Polarity is not a concern for the coil itself, but proper connection to the rectifier circuit is essential for correct operation.
Connect the Coil to a Rectifier Circuit:
The receiver coil generates an AC voltage when placed in the electromagnetic field of a transmitter coil. This AC voltage must be rectified and regulated to provide a stable DC output. Use a bridge rectifier and a voltage regulator circuit for this purpose.
Align the Receiver and Transmitter Coils:
For optimal power transfer, ensure that the receiver coil is aligned with the transmitter coil. Misalignment can significantly reduce efficiency.
Test the System:
Place the receiver coil within the operating range of the transmitter coil. Measure the output voltage and current to ensure they meet the requirements of your application.
To demonstrate the use of the receiver coil, you can connect it to an Arduino UNO to monitor the voltage output. Below is an example code snippet:
// Example code to monitor the voltage output of a wireless power receiver coil
// using an Arduino UNO. The voltage is read via an analog pin and displayed
// on the Serial Monitor.
const int voltagePin = A0; // Analog pin connected to the rectified output
float voltage = 0.0; // Variable to store the measured voltage
void setup() {
Serial.begin(9600); // Initialize serial communication at 9600 baud
pinMode(voltagePin, INPUT); // Set the voltage pin as input
}
void loop() {
int sensorValue = analogRead(voltagePin); // Read the analog value
voltage = sensorValue * (5.0 / 1023.0); // Convert to voltage (5V reference)
// Print the voltage to the Serial Monitor
Serial.print("Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(1000); // Wait for 1 second before the next reading
}
Note: Ensure the rectified output voltage does not exceed the Arduino's input voltage range (0–5 V).
