– The aim of this study is to present a very simple, intuitive and feasible tool: the D-transform between converters. This new method proposes to find a control equation of any pre-defined control law from one converter to another power converter. The central goal is to take maximum advantage of the robustness offered by the originator nonlinear control law. Although there is the possibility of more than one conversion, some candidates show good performance in terms of transient overshoot, settling time and steady-state regulation. The stability proof is disposed individually for each generated equation. The performance of D-Controllers is verified through Hardware In the Loop (HIL) simulations. A small overshoot under input and load perturbations is achieved for the buck-boost example. Finally, a experimental validation using a buck converter is given to illustrate the application method and the nonlinear control design.

This work presents an alternative for the connection of switched capacitor ladder cells in order to obtain a high cc-cc conversion rate. The proposed modification consists in split the output capacitor of the first cell, being they the input capacitors of a second ladder cell, that is, a series connection with integration of elements is performed. The modification in the output capacitor allows the connection with a reduced number of components. These advantages make the structure suitable for converters with a high conversion rate, step-up or step-down. The topology, the ladder cell and connection analysis, the equivalent circuit and cascade connection loss analysis are studied. The theoretical analysis is validated through experimental results in a prototype of 200 V for 50 V and 200 W of power. Additionally, a comparison with the classic ladder connection and other high-gain converters is presented to highlight the advantages and disadvantages of the proposed structure.

– This work presents a simple and accurate analytical model for power MOSFET loss calculation. A comparative analysis among commonly used methods in the literature and the proposed approach is presented. The proposed model uses a simplification of the charge behavior of MOSFET parasitic capacitances. Junction temperature variation with frequency is considered. Thermal measurements are used to validate the model up to 300 kHz. Results demonstrate the accuracy of the proposed model using two different MOSFET part numbers, of superjunction and conventional silicon technology. Due to the accuracy and simplicity of the model, it is recommended for use in analyses where many operating points are tested (voltage, frequency, power), genetic algorithms, and database applications.

This paper presents the analysis of the integration of two three-phase half-controlled boost converters, operating in discontinuous conduction mode (DCM), to the auto-connected 12-pulse rectifier. The proposed structure shows a reduced current harmonic content compared to the traditional 12-pulse rectifiers, being a simpler and effective alternative to using rectifiers with higher pulse numbers. It also presents a greater range of possibilities for regulating the output voltage, without the use of synchronization algorithms or rigorous control techniques, being possible to send to all controlled switches, the same command signal, resulting in a simpler logic. Another advantage of using the proposed technique is the employment of a single-loop voltage control scheme, reducing the computational and financial cost by eliminating some elements such as current sensors. Moreover, the proposed strategy provides soft commutations (Zero-Current-Switching ZCS). In this work, a small-scale prototype was implemented, aiming to obtain a structure capable to operate in a wide range of line frequencies, without requiring any additional complex techniques. In this regard, the developed structure is capable to work as a Power Factor Correction (PFC) stage in a wide range of input frequencies (30Hz 120Hz) with a Total Harmonic Distortion of the input current (THDi) of less than 2.19%.
