PURPOSE:To reduce a torque ripple by bringing reference triangular wave frequency to 3M times as many as reference sine wave frequency and each delaying the phase of second - fourth inverters only by a predetermined phase angle to a first inverter. CONSTITUTION:A multiple type PWM inverter is ...
Pulse width modulation technique is always applied in the design of inverter. The output voltage waveform of inverter is not relative pure sinusoidal, especially if it is applied linear pulse width modulation. A non-pure sinusoidal voltage waveform can affect the life time of inverter and also the...

Voltage source converter based high voltage direct current transmission (VSC-HVDC) is a new transmission technology based on pulse-width modulation (PWM) and insulated gate bipolar transistor (IGBT) [34,35]. The German BorWin2 offshore wind power project, it realized grid-connected transmission ...
The existing controllable reactors are primarily classified into five categories [18]: traditional, thyristor-controlled, magnetic-controlled, pulse-width modulation (PWM) controllable, and superconducting controllable reactors. Traditional controllable reactors exhibit discrete changes in the inductance values, ...
