What it represents
A converter arrangement using the documented resonant inductive/capacitive network and magnetic transfer path.
On a schematic, identify the resonant inductor/capacitor, magnetising inductance and switching bridge and trace the secondary output and resonant-controller interface. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
The LLC designation identifies a resonant network arrangement; it does not state component values, switching limits or efficiency.
The preview is a conceptual topology reference rather than a complete power-stage circuit. Switching sequences, magnetic design, component selection and control/protection details belong in the equipment design documentation.
How to read it
- Identify the resonant inductor/capacitor, magnetising inductance and switching bridge.
- Trace the secondary output and resonant-controller interface.
Information to show or reference
- Label the resonant inductor/capacitor, magnetising inductance and switching bridge.
- Cross-reference the secondary output and resonant-controller interface.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
The LLC designation identifies a resonant network arrangement; it does not state component values, switching limits or efficiency.
