Cascaded multilevel inverter, diode clamped inverter, modular inverter and sinusoidal pulse width modulation. 1.
The principle of operation, theoretical basis of pulse width modulation and capacitors voltage balancing method of a five-level modular inverter are presented. Several load scenarios are considered such as operation with different modulation indices, load power factors, imbalance load, symmetrical and asymmetrical faults. In addition, a scenario with utility interface of storage system is considered. Computer simulations in Matlab Simulink environment are used to validate the operation of the inverter.
