How to control a three-phase inverter using current control?
From tracking the phase, the control of a three-phase inverter can be practically implemented using current control. Given a PLL system and current control algorithm, a Simulink model will be used to simulate the control of a three-phase inverter.
What does a three-phase inverter convert?
The voltage source inverter (VSI) is a commonly used power inverter. It converts a DC voltage into a three-phase AC voltage. So a three-phase inverter is required.
How does a three-phase three-level inverter work?
When the rotating voltage vector falls into a certain sector in a three-phase three-level inverter, adjacent voltage vectors are selected to synthesize the desired rotating voltage vector based on the principle of vector synthesis, resulting in PWM waveforms in three-phase.
Does a 3 phase inverter have harmonics?
The output voltages of a three-phase inverter have the shape of a square wave, not a pure sinusoidal wave, so they include many harmonics.
What does VSI stand for in a three-phase inverter?
For the three-phase inverter, we sub-divide into VSI (voltage source inverter) and CSI (current source inverter). We study the VSI (voltage waveforms, harmonics, calculation of the output voltage).
How many transistors does a three-phase VSI have?
The three-phase VSI has six transistors to form a bridge structure with three legs. The voltage source inverter (VSI) is a commonly used power inverter. It converts a DC voltage into a three-phase AC voltage.
