AI Technical Summary
Technical Problem
In hybrid electric and electric vehicles, the excitation signal for resolvers often results in overcurrents beyond the actual application range due to transient responses, leading to increased driver size and cost.
Method used
An apparatus and method that incrementally increase the voltage of the excitation signal up to a target voltage based on transient currents flowing into the coil, using a processor to control the sine wave generation and amplification units, thereby preventing overcurrents and reducing driver size.
Benefits of technology
This approach effectively limits transient currents within the actual application range, reducing the size and cost of the driver by step-wise voltage adjustment, preventing overcurrents and optimizing resolver operation.
