Simulation study of non-electrical contact power supply system for electronic scales based on advanced control algorithm and electromagnetic coupling

This paper presents the design and implementation of the non-electric contacting power supply system for the electronic scale, which mainly focuses on improving power transfer and measurement accuracy.The whole system architecture includes electromagnetic coupling, an advanced algorithm of control, and safety.Simulation results have shown that, under standard conditions, it is possible to reach a high power transfer efficiency higher than 90% while keeping voltage regulations within 1% and limiting current ripple to below 1.8%.Therefore, this provides a measurement resolution of 0.1g for the system while granting stable performance for a variety of conditions in both coupling and load.Protection mechanisms set within the system ensure reliable operation; fault detection time is less than 10s.The proposed method represents a relatively good guide for non-contact power supply towards precision measurement, thus solving the challenge of WPT in an electronic scale system.
