Resolver Excitation Circuit Overcurrent Protection

The patent implements preliminary protection actions by incorporating a circuit protector that proactively detects and responds to overcurrent and short-circuit conditions before they can cause damage. The protector includes detection circuitry that monitors current levels and automatically terminates operation when abnormal conditions are detected, preventing harm to the excitation signal generation circuit and connected components.

The circuit protector serves as an intermediary component between the excitation signal generation circuit and the potential harmful effects of overcurrent and short-circuiting. This mediator detects abnormal conditions and intervenes by controlling the switching elements to terminate operation, thereby protecting the main circuit without requiring fundamental changes to its structure.

The patent merges the protection function with the existing circuit structure by integrating the circuit protector into the excitation signal generation pathway. The protector utilizes the same switching elements and control signals already present in the circuit, combining protection functionality with the operational components rather than adding entirely separate protection systems.

The circuit protector is designed to handle multiple protection scenarios (overcurrent protection and short-circuit protection) using a unified detection and response mechanism. The same detection circuitry and switching control serve both protection functions, making the protection system multi-functional and reducing the need for separate dedicated protection components for each hazard type.
