Ac-Dc Conversion TRIZ Cases
- Photovoltaic Cell for Converter Controller Auxiliary Power
A photovoltaic cell provides auxiliary power to the controller, eliminating complex batteries and enabling safe startup of normally-on switches.
- Inverter Phase Synchronization via Wobble Signal PLL
A further synchronization unit aligns periodic wobble signals with the power supply grid using phase-locked loops.
- DC Bus Voltage Control Circuit for Wind Turbines
Segmented DC buses with independent switches dissipate regenerative energy during grid faults to prevent voltage overshoot.
- Charge Pump Voltage Regulation via Feedback Control
A charge pump circuit adjusts input voltage through a feedback unit to maintain stable output levels.
