This paper examines a position sensorless modulation strategy, called V-θ control, for six-switch fully-controlled rectifiers (inverters) for surface permanent magnet (SPM) generators in small-scale wind turbines. In this strategy, the SPM generator torque is commanded by controlling the magnitude of the phase voltage and its phase shift with respect to the current waveform. Simulated results obtained...
This paper deals with a 30KW Interleaved DC/DC Converter for hybrid electric vehicle power supply system which is composed of a fuel cell/battery as primary source and a supercapacitors module as an intermediate energy storage system. A dedicated DC-DC converter is studied, where the design and control are the result of considerations on energy efficiency. The analysis of the efficiency shows that...
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...
