What are the different types of inverters?
Inverters are mainly classified into two main categories. The inverter is known as voltage source inverter when the input of the inverter is a constant DC voltage source. The input to the voltage source inverter has a stiff DC voltage source. Stiff DC voltage source means that the impedance of DC voltage source is zero.
What is a three-phase voltage source inverter (VSI) with SPWM?
A three-phase Voltage Source Inverter (VSI) with SPWM (Sinusoidal Pulse Width Modulation) is a type of inverter that converts DC voltage into three-phase AC voltage with sinusoidal waveforms. It works by varying the pulse width of a high-frequency carrier signal according to the instantaneous amplitude of a reference sinusoidal waveform.
What is a voltage source inverter?
The inverter is known as voltage source inverter when the input of the inverter is a constant DC voltage source. The input to the voltage source inverter has a stiff DC voltage source. Stiff DC voltage source means that the impedance of DC voltage source is zero. Practically, DC sources have some negligible impedance.
How does a reference waveform affect the output current of an inverter?
The reference waveform may be varied in amplitude and phase with respect to the grid and the output current of the inverter follows the reference. The output current waveform is ideally not influenced by the grid voltage waveform quality. It always produces a sinusoidal output current.
What is a single phase inverter?
These categories are briefly discussed here. A single-phase inverter converts DC input into Single phase output. The output voltage/current of single-phase inverter has exactly one phase which has a nominal frequency of 50HZ or 60Hz a nominal voltage. The Nominal voltage is defined as the voltage level at which Electrical system operates.
What is the function of a DC inverter?
The main function of the inverter is to convert DC input voltage to a AC output voltage of the desired magnitude. The output voltage waveforms of the ideal inverters should be sinusoidal, however the waveform of the practical inverters are non sinusoidal and contains different harmonics.
