Current/Voltage Measurement TRIZ Cases
- Battery Fault Prediction Using Lookup Table Status Monitoring
Lookup-table monitoring compares current battery status data with prior patterns to predict latent faults before shorts, damage, or fire.
- Voltage Stability Monitoring Under Renewable Output Fluctuations
Adaptive limit prediction and condition-based calculation cut convergence risk while tracking power-system voltage stability.
- Electricity Meter and Circuit Breaker Integration for Remote Cut-Off
A bistable relay in the circuit breaker lets the meter handle remote line cut-off without its own switch, reducing size, cost, and contact blackening.
- Circuit Breaker Reclosing Using Shunt Reactor Current Derivative
Line voltage is derived from shunt reactor current change, enabling more accurate circuit breaker reclosing under variable frequency.
- Modular Power Tile Fault Detection Using SSTDR Signals
SSTDR signal injection tracks reflected patterns in live power cables to locate impedance faults and schedule maintenance without shutdown.
- Three-Phase Open-Phase Detection Using Photocoupler Pulse Logic
Photocoupler pulse signals and AND logic detect open phases and interruptions in three-phase AC power without slow circuit adjustment.
- USB-C Receptacle Water Detection Before Safe Power Delivery
Multiple current sources and PDIC voltage sensing distinguish cable connection from water pull-down, helping prevent USB-C pin corrosion.
- Charge Pump Overcurrent Detection Using Voltage Comparison
Voltage-based comparison detects charge pump overcurrent within nanoseconds, protecting charging-path switches during fast battery charging.
- LDO Load Sharing Using Variable Dividers and External Pass Elements
Variable divider control shifts LDO current to external pass elements at high load, reducing die heating while preserving startup and bandwidth.
