AI Technical Summary
Existing methods to mitigate audible output in charging circuits, such as using reinforced physical connections, damping materials, or superimposing cancellation signals, are limited by increased component size, cost, or inefficiency, particularly in contexts where packaging constraints are stringent.
A mitigation controller monitors the frequency of voltage at an input node of a charging circuit and temporarily disables or modifies power supply to the system load when mitigation conditions are met, using parameters like frequency, amplitude, and decibel thresholds to prevent audible output.
Effectively reduces or eliminates audible output by dynamically managing power supply, avoiding component vibration and potential mechanical failure while maintaining efficient operation and adhering to packaging constraints.
