Electric Generator Control TRIZ Cases
- Downhole Active Rectifier for Variable-Flow Power Generation
A sensorless active rectifier turns variable turbine AC into constant DC downhole, avoiding flow-kit swaps and drilling downtime.
- Initial Excitation Circuit for Generator Startup Fault Diagnosis
Battery-fed pre-excitation and breaker diagnostics help a vehicle generator start reliably despite weak residual flux and brush contact faults.
- Generator Control Mode Switching for Engine Load Impact Recovery
Switching generator control from voltage feedback to speed-based mode during load impacts cuts torque peaks, limits engine speed drop, and speeds recovery.
