This paper deals with the design and analysis of new h-bridge based single and three phase cascaded multilevel inverter. It has two types of sources: symmetric and asymmetric source. In this topology asymmetric source is preferred because it provides large number of output voltage level with minimum number of switches. This new H-bridge based cascaded multilevel inverter is able to increase output...
This paper presents a novel dynamic model of a single-switch class-E inverter. Both the transient and steady-state behaviors of main variables are derived using a multifrequency averaged (MFA) modeling method. The analysis of the boundary conditions reveals that, under some approximations, the performance of the generalized averaged model is close to that of the “exact” or topological one. A detailed...
Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial...
