Conversion With Intermediate Conversion To Dc TRIZ Cases
- Half-Bridge Converter Startup Duty Cycle Control
Dynamic duty cycle adjustment prevents hard switching and reduces energy loss during converter startup while maintaining steady state efficiency.
- Switching Control Circuit Terminal Merging for Soft Start and Power Limiting
A switching control circuit integrates soft start and power limiting functions into a single terminal to reduce IC package size.
- Inverter Pulse Mode Control for Efficiency and Harmonic Reduction
Pulse mode inverter control adjusts output frequency and width to conserve energy, reducing harmonic distortion while maintaining DC bus voltage.
- Voltage Step-Down Circuit for Power Converter Imbalance
A voltage step-down circuit stabilizes DC bus voltage in power converters by dynamically adjusting switching elements.
- Switching Power Supply Current Detection via Transformer Secondary Voltage
A control part calculates output current from a current transformer secondary voltage to reduce sensor count in switching power supplies.
- Variable Speed Drive Input Filter for High Frequency Distortion
Active converter input filter attenuates line-to-ground voltage transients and common mode currents, protecting motor bearings from insulation failure.
- Intermittent Oscillation Frequency Control for Switching Power Supply Noise Reduction
A semiconductor device delays switching state changes to shift oscillation frequencies outside the audible range.
- Resonant Power Converter Controller for Acoustic Noise Reduction
Integrated controller modulates switching frequency via feedback and feed-forward signals, disabling burst signals in the audio band to reduce acoustic noise.
