Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...
A detailed model and analysis of a five-level cascaded H-bridge (CHB) multilevel inverter with different current control methods are presented. Simulation models the CHB hysteresis controller, PI controller using SPWM technique predictive have been built to demonstrate system performance regard load THD reference tracking. In controlling current, controllers problem ripple phase lag, respective...
In recent years, voltage source multilevel inverters are being applied extensively in industry as they have many advantages compared to conventional two level inverters. Some of these advantages such as higher output voltage at low switching frequency, low voltage stress (dv/dt), lower Total Harmonic Distortion (THD), less Electro-Magnetic Interference (EMI), smaller output filter and higher fu...
The developments in power electronics technology have led to the developments in the wind energy conversion system (WECS). The output voltage of the WECS depends on the speed of the wind, which is not constant. Hence, a power conversion unit is required to maintain the output voltage of the WECS constant. This paper presents the design of a boost converter and a voltage controller for maintaini...
