Conversion Without Intermediate Conversion To Dc TRIZ Cases
- Single Phase to Three Phase Power Conversion with Common Neutral
Phase shifting inverting circuit creates stable three phase power with common neutral, reducing conversion losses and improving integration.
- Matrix Convertor Intermediate Voltage Phase Control
A matrix convertor controller sets a lower limit for the intermediate voltage phase connection period to stabilize output.
- Matrix Converter Parallel Switch Modules
Parallel bidirectional switch modules in matrix converters reduce surge voltage and rated current restrictions to enable higher power capacity.
- Multi-phase Transformer with Adjustable Windings
A multi-phase transformer uses adjustable polygon windings to modify voltage ratios without adding extra coils.
- Power Converter Filter with Shared Neutral Inductance
A power converter filter relocates neutral inductance to live lines using a shared core design.
- Frequency Converter LO Signal Harmonic Elimination
A frequency converter uses a phase resolution variable local oscillator to multiply received signals for heterodyne conversion.
- Phase Shifting Transformer Power Cell Voltage Drive
Cascaded power cells receive phase-shifted transformer voltages to generate three-phase AC output while reducing semiconductor device count and cost.
