Diagnostyka strategii sterowania napędów z silnikami PMSM

Implementation of the AC drive control takes into account the wider frequency control voltage, which is the best solution in terms of power and control the economics of modern propulsion systems. Projected for this purpose frequency inverters, which are an integral part of the line converter, the circuit current and voltage of the inverter current and voltage. Widely applied to power systems voltage with a frequency pulse width modulated PWM. Use a switching frequency range of 5-50Hz, which is obtained current waveforms similar to the sine wave shape, and what makes it such propulsion systems are characterized by high efficiency and power density. Opportunities of this type power supply, determined the prevalence of high-power circuits for IGBT inverter. At power up to 150 kW are used IPM modules containing current and temperature sensors, controllers and insulated against short circuit protection systems so that the entire power system is secure and complete.
