Control of Medium Voltage Multi-phase machines: Implementation of Minimum loss Synchronous Optimal Modulation with Neutral Point Balancing

摘要: The total loss of an inverter can be reduced by reducing switching losses and harmonics losses. However, the increases with reduction frequency special technique is required to get overall at minimum value. synchronous pulse width modulation described here uses a minimization criterion function used low while getting acceptable for medium voltage multiphase drives. approach fixed set optimized patterns generated programmed minimizing function. Weighed Total Harmonic Distortion normalized DC link as parameter it directly related in system. In order optimization angels fast any value index, real time pattern generation method instead storing values into memory. This has possibility adding offsets overcome effects such balancing transient normalization. number pulses amplitude becomes very high keeping range. makes complication calculation well implementation Synchronous Optimal PWM modulation. It therefore, asynchronous space vector prioritized interrupt signal effectively switch from one other whenever required. Multilevel inherent problem imbalance, which must addressed smooth operation. Many alternatives are purposed choice made work both Further, stability needs system might force out leading many technical flaws. operation optimal requires, processing executing processor. As such, Virtex-5 ppc440 FX30T operate frequency. During this thesis, advanced simulated using computing software’s implemented lab. A six-phase induction machine rating 11.7 kW lab help three-phase three-level inverter. Xilinx ISE suite communicate between hardware software build embedded design.
