Analysis and Design of Overcurrent Protection for WPT Systems
However, the class-D inverter may suffer from a large output current due to accidental variations of the load resistance and mutual inductance, which may potentially lead to device
The class-D inverter's output current can be automatically protected to a safe value by the proposed over-current protection circuits. Compared to active protection, the current detection circuit and related control circuit are not required in the proposed method, which reduces the control complexity and is easy to implement.
Inverter overload protection prevents the inverter from delivering more power than its rated capacity. When too much current flows through the inverter, the protection circuit either reduces the output or shuts down the inverter entirely. This stops damage to internal components and connected devices.
Two passive over-current protection circuits for WPT systems with class-D inverter are proposed in this paper. The class-D inverter's output current can be automatically protected to a safe value by the proposed over-current protection circuits.
Devices like circuit breakers or electronic current limiters are commonly used to carry out this protection. Overcurrent protection is especially useful in industrial setups where machinery start-up loads fluctuate. It also works with inverter overload protection to prevent cascading failures across your power system.
