Abstract
Weight minimisation and high efficiency requirements set limitations on the Matrix Converters input filter. It is therefore important to suppress the potential input resonance without using a large damping resistor. The existing solutions trade off the AC drive output performance against the input side active damping. This paper draws important insights from a comprehensive overview of relevant literature. It proposes a different and novel approach based on optimal control design. Under this approach, a high performance closed loop control is performed on the output side, while the input current spectrum is effectively adjusted by strategic shaping of the output current noise. As a result, the desired damping of the input resonance is achieved. © 2019 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
