Transformers/Inductances Circuits TRIZ Cases
- Current Sense Transformer Opposing Windings for Accurate Breaker Sensing
Opposing primary winding turns create the target turns ratio without excess wire length, reducing heat, space limits, and sensing errors.
- MEMS Variable Inductor Structure for Tunable Inductance Control
Electrostatic MEMS motion changes coil and substrate spacing to tune inductance after fabrication for multi-band IC blocks such as VCOs and LNAs.
- Shielded Variable Inductor Layout for Interference and Q Control
A nested secondary inductor and voltage-controlled switch block external interference while tuning inductance and quality factor.
- Controlled Switching Device for Transformer Inrush Current Mitigation
A controlled switching device calculates optimal electrical angles to synchronize circuit breaker closing.
- Wireless Power Transmission Impedance Control
Dynamic impedance adjustment prevents voltage rises in reception circuits by adapting to phase-specific power consumption.
