Electric Power TRIZ Cases

A wireless power transmitter calculates a signal strength limit using receiver sensitivity and voltage limits to prevent over-voltage damage during charging.

A gate driver boosts the charge enable transistor gate potential above cell voltage to fully turn on high-side NFETs.

Wheel-based generator assemblies harvest mechanical energy from container movement to power electronic tracking devices, eliminating external charging needs.

A UPS controller detects voltage and current values to identify abnormal portions within the power system.

A tone power scheduler directs RF energy via beamforming to specific receivers.

A charging device with adaptive current limiting protection adjusts flow based on detected voltage levels.

Programmable controller manages variable voltage drop blocking devices across multiple battery outputs.

A power recovery controller applies pulsed current at a battery's resonant frequency to enhance charging efficiency.

A battery device power protection circuit uses a switch to isolate the main system from the battery during storage.

Power converters manage individual stack interactions with the bus, allowing maintenance and diagnostics without disrupting global battery operation.

A power tool energy source monitoring system uses switch control logic to extend operation time based on trigger press duration.
