Exact inversion with a boost DC/AC power converter
2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015The use of DC-DC boost-based switched converters for DC-AC step-up inversion applications has been long handicapped by the fact that it requires non-offset, periodic current reference profiles that satisfy an Abel differential equation of the 2nd kind, and this is a challenging problem because the corresponding vector field becomes nonsmooth in zero ...

Predictive power control of an AC/DC/AC converter
Fourtieth IAS Annual Meeting. Conference Record of the 2005 Industry Applications Conference, 2005., 2005This paper presents a new control scheme for a regenerative AC/DC/AC converter using model based predictive control. The control strategy minimizes quality functions, which represent the desired behavior of the converter. At the inverter side, the load current error is minimized, while at the input side, the active and reactive powers are controlled ...

Monte Carlo simulation of AC/DC/AC power converter distortion
2001 IEEE Porto Power Tech Proceedings (Cat. No.01EX502), 2002Probabilistic analyses of AC/DC/AC power converter harmonic and interharmonic distortion are performed by using the Monte Carlo simulation. Starting from previous experiences of some of the authors, an analytical and simplified conversion system model recently proposed is recalled and discussed. A new model of the control system is presented. Different
