Inverter Control
Optimize PWM for:
- Losses (discontinuous, staggered clocking)
- Control objectives e.g. for symmetries in multi-level topologies, distribution of losses, minimization of specific harmonics
- Harmonic spectrum of the output current (minimization of acoustic emissions, prevention of excitation of known system components)
Inverter Topologies:
- Voltage and current link converter
- Multilevel topologies (MMC, ANPC, NPC, FC)
System Topologies:
- Wind turbines, offshore grids, grid couplings, HVDC systems, electrical machines
Regulatory Procedure:
- Current control methods (discrete, continuous, VOC, MPC)
- Active attenuation (LC filter, passivity adjustment)
- Model Predictive Control
- System control (MMC, island grids, offshore grids, grid supporting and forming controls, black start).
Inverter Topologies at 25V Lab Scale:
- Two-point converter and three-point converter (NPC)
- Modular Multi-Level Converter (MMC)
System Topologies at 25V Lab Scale:
- Over 10 freely configurable back-to-back converters to represent a wide variety of loads and sources – from diode load, power load to wind turbines
- Electric machines (SM, DFIG, ASM) as load source or sink, optionally with inverters and/or back-to-back machine sets
- Various passive loads (RLC)
