Abstract :
A practical power converter based on a high-frequency primary converter and a matrix secondary converter is discussed. The matrix converter is used as a cycloconverter. The high-frequency link power is converted to a 50 Hz sinusoidal output voltage loading with a nonlinear load in general. The results achieved to date indicate that the composite converter can meet the demands of high efficiency, high dynamic response, and low cost. Simulations were used to design the converter topology and the control strategy, while practical results show the performance of the composite converter system, which can be implemented in renewable energy systems.<>
