Power Supply Lines TRIZ Cases
- Soft-Start Control Circuits for DC-DC Converter Inrush Current
Soft-start control circuits regulate control signal variation during startup, shortening uncontrolled state duration and preventing inrush currents.
- Thyristor Switching for Railway Phase Separation
Zero-crossing switching suppresses over-voltage and over-current during phase separation.
- Buck Converter Soft-Start Control Voltage Rollback
A Buck converter system manages soft-start control voltage to prevent component damage during high-side MOSFET activation.
- One-Volt Bandgap Reference Circuit Architecture
A bandgap reference circuit generates a stable one-volt output using super-PTAT current generation and adjustable feedback dividers.
- Self-regulating Semiconductor Heater with Biasing Network
A self-regulating heater uses a semiconductor element biased by a network to control current conduction and stabilize temperature.
- Railway Transformer Inrush Current Reduction
A railway transformer energization method measures magnetic remanence to determine optimal breaker closing timing.
- Reference Voltage Generating Apparatus Removing Temperature Invariant Current
A reference voltage generating apparatus removes temperature invariant current components through a dedicated branch circuit.
