A multilevel converter is a system that generates a limited number of voltages as output during the desired periods of time. It consists of switching devices and capacitors. The number of voltage levels depends on two things: the number of elements and the selected topology. The spectrum of the generated waveform can include the desired fundamental harmonic value. The voltage level and period of time of the transition is calculated. This way the desired output spectrum can be potentially generated. Also the multilevel converter behavior can be controlled by the output pattern so the power flow of a system can be controlled.
The coil is connecting the system and the grid so a rectifier or an inverter can be obtained. The system can be considered as an inverter for two, three and n-level converters. At any time, the most appropriate instant of switching can be selected at any time by using different strategies, this is called modulation. The global control system of the converter can adapt the modulation conditions to each situation. The converter can be used in several applications where a wide bandwidth is required because the modulation conditions can be adapted using the global control system of the converter. Pulse width modulation (PWM) is a techniques can generates output waveforms with different amplitude, phase and frequency just selecting the suitable average time between both levels.
