Ac-Ac Conversion TRIZ Cases
- Parallel Inverter Synchronization via Optical Timing Signals
Common controller generates gate drive signals for parallel inverters using optical cables to synchronize switching timing.
- Parallel Power Controller Switch-On Time Determination
Pre-calculating controller sequences minimizes total current fluctuations and reduces flicker in AC systems without iterative optimization.
- Current-Fed High-Frequency Isolated Matrix Converter
A current-fed high-frequency isolated matrix converter adjusts current vector sequences to achieve zero voltage switching across all switches.
- Inverter Pre-Charging Circuit Segmentation for PCB Design Freedom
Segmenting the pre-charging circuit into distinct relay and resistor paths resolves PCB design constraints while maintaining over-current protection.
- Multilayer Circuit Substrate Feedback Wiring for Piezoelectric Inkjet Drivers
Feedback wiring patterns on a multilayer circuit substrate route modulation signals to reduce switching losses in high-speed piezoelectric inkjet drivers.
- Capacitorless AC-AC Voltage Booster Using Bidirectional Switches
A capacitorless AC-AC voltage booster uses bidirectional switches driven by PWM signals to transform primary voltage levels without rectification stages.
