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...

In this paper, the marine predator algorithm (MPA) is proposed for solving transcendental nonlinear equations in a selective harmonic elimination technique using multilevel inverter (MLI). It proved its suitability and supremacy over other (SHE) techniques used recent research as it has good precision, high probability of convergence, improving quality output voltage.

Two batteries are used as sources investigate performance of inverter. system can provide 220 volts 50 Hz AC supply wit...

This work presents the two space vector pulse width modulation (SVPWM-I and SVPWM-II) strategies for eleven-level (11L) asymmetric cascaded H-bridge (CHB) multilevel inverter (MLI). Depending on isolated structure nonappearance of capacitor voltage balancing issues, CHB MLI is favoured. These days, SVPWM control method accomplished superior consideration among diverse PWM methods. In common, st...

In this paper a transformerless Static Synchronous Series Compensator (SSSC) to increase the power capacity of a 230 kV transmission line is proposed. In order to eliminate the transformer, a 15-level cascade H Bridge (CHB) inverter is employed within the proposed compensator structure to inject reactive power to the transmission line. The theory of instantaneous p-q power using in the compensa...

<span lang="EN-US">The conventional two-level inverter becomes no longer has the ability to cope with high-power requirement, so this paper discusses two very common topologies of multilevel like modular multi-level converter (MMC) and cascaded H-bridge (CHB) for induction motor drive applications.

Nowadays Multilevel inverters are widely using in various applications. Modulation strategy at fundamental switching frequency like, SHEPWM is prominent technique to eliminate lower order of harmonics with less switching losses and better harmonic profile. The equations which are formed by SHE are highly nonlinear transcendental in nature, there may exist single, multiple or even no solutions f...
