How to

How to use a circuit diagram template.

  1. 01Start from a template or blank canvas

    Open the circuit diagram maker and select a full-bridge WPT sender template that matches your power level and frequency.

  2. 02Place the full-bridge inverter stage

    Add the four switches (MOSFETs or IGBTs) in an H-bridge configuration, along with gate drivers and bootstrap capacitors.

  3. 03Insert the resonant compensation network

    Connect the primary coil and compensation capacitors (series, parallel, or LCC) to achieve zero-voltage switching.

  4. 04Add control and sensing blocks

    Include the microcontroller or gate driver IC, current/voltage feedback, and any protection circuitry.

  5. 05Annotate and export

    Label key nodes, component values, and operating parameters, then export the diagram as SVG, PNG, or PDF.

FAQ

Questions about circuit diagram templates

What is a full-bridge WPT sender?

A full-bridge WPT sender is the transmitter-side inverter that converts DC input to high-frequency AC for driving the primary coil in a wireless power transfer system.

What frequency do these circuits operate at?

Most full-bridge WPT senders for EV wireless charging operate at 85 kHz, as specified by the SAE J2954 standard, but other frequencies between 20 kHz and 150 kHz are also used for lower power applications.

Can I edit the example circuit diagrams?

Yes, every example is fully editable. You can open it in the circuit diagram maker, change component values, replace parts, and add or remove sections to fit your design.

What components are typically shown in a full-bridge WPT sender diagram?

Typical components include four power switches (MOSFETs or IGBTs), gate drivers, bootstrap capacitors, resonant capacitors, the transmitter coil, and sometimes an impedance matching network.

How do I make my own WPT sender full bridge circuit diagram?

Use the generator above. Start from a template, modify the circuit to match your design parameters, and export the final diagram for documentation or PCB layout.
