The main basic parameter of the inverter is the Nominal AC power Pnom, that is the maximum power the inverter is able to deliver to the grid in any conditions. Some manufacturers specify also a Maximum AC power Pmax, as a power which may be attained in specific conditions.
The function of an inverter is to transform low-quality AC power from the grid or power produced by a DC battery or other intermittent renewable energy sources into high-quality AC power that may be used to power delicate electronic equipment.
The AC side voltage of the inverter is u c = 2 k c λ U dc sin ( ω t+ δ ). k c is the voltage conversion coefficient of the inverter. ω is grid rotation angle frequency. 3. The amplitude and phase control steady power model The amplitude λ and phase δ control strategy is shown in Fig. 3.
These applications mainly use voltage source inverters. Voltage source inverters are classified based on the no. of levels in output voltage as two-level inverter and multilevel inverters (diode clamped, flying capacitor and cascaded H-bridge).
This paper presents a comprehensive overview of PWM techniques for two-level voltage source inverters and provides a comparative analysis of commonly employed PWM techniques, including sinusoidal PWM, zero-sequence injection PWM, third-harmonic injection PWM, space vector modulation, and optimized pulse pattern with selective harmonic mitigation.
In order to simplify the analysis, the internal resistance R of the inductance is ignored and A phase grid voltage is taken as the phase reference. δ angle is the phase angle of inverter output voltage relative to grid reference voltage.
