Can a 3-level 3-phase inverter SVPWM be implemented?
The algorithm can be used to implement the 3-level 3-phase inverter SVPWM. However, because the impact caused by the dead-time and the unbalance of the DC side voltage are not considered, further research is required. Therefore, we must pay special attention to the limitation of the method.
Why is SVPWM used in 3 phase inverter control system?
Table 5. The SVPWM has been widely used in 3- phase inverter control system because; it has a higher utility efficiency of DC-side voltage than the sine pulse width modulation (SPWM). Although the SVPWM has many advantages, it is difficult to implement.
What is space vector pulse width modulation (SVPWM)?
The space vector pulse width modulation (SVPWM) has been widely used in 3- phase inverter control system. The most effective way for the MCU implementation of the SVPWM is the center-aligned PWM, because the PWM module in the MCU can generate the center-aligned PWM easily.
What is a 3-level inverter?
To improve the system efficiency of the 3-phase inverter, the 3-level or multilevel inverter is becoming more popular. Compared to the 2-level inverter, the 3-level inverter has more power switches (up to 12); this means the 3-level inverter has many more vector sectors than the 2-level inverter.
