In the three-phase micro-inverter developed at the Florida Power Electronic Center (FPEC), maximum efficiency is achieved when it is operating at close to its rated power. At lower power, load independent loss becomes a larger part of the overall loss and negatively impacts efficiency. It is therefore advantageous to operate each phase as close to its rated power as possible. One way to accomplish...
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...
