Dc Network Circuit Arrangements TRIZ Cases
- Cascaded Inverter Power Architecture for Lower Cable Loss
By cascading power modules and DC-to-AC units, this case raises voltage to cut current, cable size, conversion loss, and cost.
- Dual-Switch Power Supply Cutoff for Short-Circuit Loads
When current persists after an upstream OFF command, a downstream switch cuts power to short-circuited loads and helps avoid fuse blow.
- Redundant Vehicle Power Supply Switchover for Fault-Tolerant Loads
A dual-supply switchover path with delimitation elements keeps safety-critical vehicle loads powered when the primary voltage drops.
- Low-Voltage Distribution Board With Serial Bus Load ID Assignment
A serial bus and ID assignment circuit simplify DC fast charger harnesses while enabling load monitoring, fault isolation, and fuse protection.
- Removable Li-Ion Battery Booster With Protected Jump-Start Switching
A compact booster uses removable Li-Ion batteries and protected switching to jump-start vehicles when standard battery connections are unavailable.
- PoE Lighting Backup Power Control for Outage Illumination
A battery pack and output control circuit keep PoE light sources powered over Ethernet during AC outages for emergency illumination.
- In-Wall Power Adapter With Swappable Control Attachment
A modular in-wall adapter separates fixed wiring from swappable controls, enabling safer post-construction upgrades like dimming, timing, and motion sensing.
- Photovoltaic Power Regulator Droop Control for Uneven Strings
Droop-based regulator control balances output voltage and current across uneven PV strings, limiting overheating and extending regulator life.
- Smart Power Switch Bank With Remote Sensing for Shared Voltage Rails
Remote sensing and multiplexed lowest-voltage selection let shared regulators feed multiple power domains while saving space and preserving point-of-load accuracy.
- Sequential Power Switching for Stable Communication Facility Startup
Sequentially energizes communication facilities after monitored power stabilization to avoid inrush overload and enable unmanned startup.
- Medium-Voltage Microgrid Control for Continuous Critical Loads
A controller coordinates dual fuel cell modes with feeder and breaker status to keep critical loads powered during grid outages.
- Multi-Controller Power Isolation for Overvoltage Fault Containment
Fuse and Zener protection isolates overvoltage on intersystem communication power lines, stopping fault spread without bulky photocouplers.
- Battery Parallel Control Circuit for Busbar Overcurrent Limiting
A timed current-limiting circuit between battery and busbar detects sustained overcurrent and reduces line current to protect battery life and reliability.
- Hydrogen Energy Storage With Condensate Recycling and Heat Recovery
Condensing fuel cell or turbine offgas recovers water for electrolysis and heat for process use, cutting fresh water demand and boosting efficiency.
- Parallel Sub-Pack Charging for Multi-Port EV Battery Packs
Multiple charge ports charge battery sub-packs in parallel, cutting EV charging time while balancing modules and limiting system complexity.
- Hybrid SOFC-PEM Fuel Cell Control for Microgrid Backup Loads
Bus-voltage-triggered PEM support lets an SOFC-based microgrid supply variable loads and backup power without batteries or combustion.
