Summary:Taking frequency-conversion speed-regulation system of high-voltage five-level active neutral point clamped ANPC as a research object, switching loss, capacitance loss and transmission loss of the system were carried on quantitative analysis on the basis of introducing mathematical topology model of ANPC five-level and PWM modulation method. The analysis results show that although loss type of the ANPC five-level topology is more, but it has significant advantage in controlling switching loss, and can make the frequency-conversion speed-regulation system of motor have more efficient operation.
