Parameter Calibration/Setting TRIZ Cases
- Solid-State Circuit Breaker Current Limiting for Fault Isolation
Controlled continuous or intermittent current limiting cuts fault current while reducing harmonic distortion and semiconductor thermal stress.
- Aircraft APU Overcurrent Threshold Control for Full Power Use
Dynamic overcurrent thresholds let an aircraft APU use available power across altitude and temperature changes while protecting equipment.
- Adjustable Current Limiting Circuit for Fast, Protected PMIC Startup
Dynamic current limiting raises startup current for heavy loads, then restrains short-circuit stress to protect PMICs during boot.
- Comparator-Based Circuit Breaker for Overcurrent Type Detection
Comparator logic distinguishes surge, short-circuit, and fault overcurrents from current and voltage thresholds for microsecond-level protection.
- Circuit Breaker Control for Fast Overcurrent Type Differentiation
Comparator-based current and voltage checks distinguish surge, short-circuit, and fault overcurrents for microsecond-level breaker protection.
- Electronic Circuit Breaker With Auto Reset and Voltage Threshold Sensing
Voltage-threshold sensing replaces temperature-dependent PPTC behavior, enabling automatic reset and reliable overcurrent protection.
- Islanded Substation Inverter Frequency Detection for Load Shedding
Frequency thresholds distinguish bulk-grid and inverter power in islanded substations, enabling targeted load shedding and overload protection.
- Transformer Overcurrent Interruption Using Through-Fault Curves
An electronic interrupter follows the transformer through-fault curve to avoid inrush trips while opening before thermal or mechanical damage.
- Circuit Breaker Coordination for Downstream Failure Backup Tripping
When a downstream breaker has an internal failure, upstream trip settings switch to emergency mode to prevent damage and maintain uptime.
- Motor Thermal Protection Using Capacitor-Based Cooling Time Tracking
A capacitor timing circuit estimates motor cooling time after shutdown to calculate remaining heat accumulation and prevent overheating on restart.
- Circuit Breaker Reconfiguration With User-Verified Field Updates
Field-configurable circuit breakers use user verification and physical presence to enable secure updates without device replacement.
- Circuit Breaker Current-Slope Detection for Inrush False Trips
A real-time current-slope algorithm separates inrush from real short circuits, preventing breaker false trips without losing fast protection.
- Bias Current Monitoring Circuit for Power Amplifier Burnout Prevention
Measured bias current is compared with a reference so the controller can cut or limit battery bias voltage before RFFE amplifier burnout.
- Load Circuit Current Profiling for Selective Overload Control
A learned current profile lets the control unit detect abnormal load behavior and shed selected circuits before the power supply reaches its limit.
- Electrical Panel Protection with Dynamic Trip-Time Curves
Dynamic trip-time curves and coordinated panel protection improve fault coverage in battery, PV, and grid-powered electrical systems.
- Adaptive Machine Safety Cutout for Power and Water Anomalies
Sensors and a controller learn normal power and water use, then trigger cutout elements when abnormal consumption patterns appear.
- Transmission Line Source Impedance Estimation From Switching Events
Uses substation voltage, current, and status signals to estimate complex source impedance from faults or switching events without created faults.
