In this work it is presented a family of six single-phase Current Source Rectifiers (CSR) topologies with asymmetric structures. The topologies present reduced number of active switches and high power factor with low harmonic distortion. Three of the shown structures represent a simplification of full-bridge CSR, replacing two switches from the original topology by two diodes. The other three structures...
In this work it is presented a review of the Multilevel Current Source Rectifiers (MCSR), aiming to reduce the number of switches and inductors, thus reducing losses, cost and volume of the converter. Despite the removal of switches and inductors, the control and PWM ensures the correct operating of the converter. Simulations are presented to validate the effective operation of the topology for five-,...
This work introduces a family of Current Source Converters (CSCs) that allows to control single-phase AC converters with two outputs independently sharing the same DC-bus. It is presented four different topologies which have their own advantages and disadvantages compared to each other. The comparison criterias are the total number of switches, the number of conducting switches per switching cycle,...
A novel approach for cascaded multilevel inverters is presented in this paper. The proposed topology is based on the association of DC/DC converters developed from an active commutation cell called EIE. The multilevel Buck EIE inverter provides an AC output and low voltage stress levels over the power semiconductor devices. The output voltage is totally controlled and follows a reference signal, which...

A novel proposal of multilevel inverter is presented in this paper. The concept of the proposed topology is based on the association of Buck EIE converters in order to constitute a multilevel inverter and to provide an ac output voltage with low harmonic distortion and low voltage stress over the power semiconductor devices. The output voltage provided by the proposed multilevel is totally controlled...
