Summary: | The invention discloses a circuit sampling system which is applied to an LCC type wireless charging system, the wireless charging system is provided with a transmitting end and a receiving end, and an inductor is arranged between the positive electrode output end of an inverter control circuit and the input end of a transmitting end main power circuit; the sampling system comprises a current sampling module; a voltage sampling module; and a processing module. The technical scheme of the invention has the beneficial effects that compared with a scheme of adding a sampling coil in a coil in the prior art, the design complexity is reduced in the aspect of structural isolation from an electric appliance, and measurement error compensation can be carried out on coil outgoing lines with different lengths through parameter adjustment; relatively accurate coil current amplitude sampling is realized; according to the technical scheme, the sampling circuit does not need to pass through an isolation device and an isolat |
