The bidirectional switch (Bi-Sw) is a power device widely used by power conversion systems. This paper presents a novel modular design of a Bi-Sw with the purpose of providing to beginner researchers the key issues to design a power converter. The Bi-Sw has been designed in modular form using the SiC-MOSFET device. The Bi-Sw uses the advantages of SiC-MOSFET to operate at high switching frequencies. The verification of the module is carried out experimentally by means of the implementation in a voltage regulating converter, where performance analysis, power losses, and temperature dissipation are performed.

“…For higher output voltage level, work done in [29] extended this topology to accommodate more dc sources. In view of three-phase applications, Jafferi Jamaludin extended the work in [29] to three-phase system, [30]. Therein, the bidirectional switches' usage was optimized following a space vector modulation control approach.…”

Splitting of a dc voltage source with two capacitors has been the approach in generating 5-level output voltage with single- and three-phase full-bridge circuits and added bidirectional switch. Associated with this configuration is the problem of voltage imbalance between the splitting capacitors. In addition, the inverter output voltage magnitude is obviously limited to the value of the split input voltage source. Presented in this paper is a unit topology for single-phase 5-level multilevel inverter, MLI. It simply consists of a full-bridge circuit, a capacitor, charge-discharge unit and a dc source. The charge-discharge unit with the capacitor is the interface between the full-bridge and the dc source. The proposed unit cell can generate a 5-level output voltage waveform whose peak value is twice the input voltage value. For higher output voltage level, a cascaded structure of the developed unit cell is presented. Comparing the proposed inverter with CHB inverter and some recent developed MLI topologies, it is found that the proposed inverter configuration generates higher output voltage value, at reduced component-count, than other topologies, for a specified number of dc input voltages. For two cascaded modules, simulation and experimental verifications are carried out on the proposed inverter topology for an R-L load. Keywords: Cascaded multilevel, Inverter, total harmonic distortion, topologies, waveform

“…Generally, due to the complex structure of the multilevel inverters, several studies have been carried out in order to reduce the number of components. For instance, Jamaludin et al [30] proposed the use of bidirectional switches with an auxiliary circuit in order to reduce the complexity of a three-phase full-bridge inverter. A hybrid circuital structure was proposed by Gautam et al [31], in which the number of controlled switches, diodes and DC sources is considerably reduced.…”

The Field Programmable Gate Array (FPGA) represents a valid solution for the design of control systems for inverters adopted in many industry applications, because of both its high flexibility of use and its high-performance with respect to other types of digital controllers. In this context, this paper presents an experimental investigation on the harmonic content of the voltages produced by a three-phase, five level cascaded H-Bridge Multilevel inverter with an FPGA-based control board, aiming also to evaluate the performance of the FPGA through the implementation of the main common modulation techniques and the comparison between simulation and experimental results. The control algorithms are implemented by means of the VHDL programming language. The output voltage waveforms, which have been obtained by applying to the inverter the main PWM techniques, are compared in terms of THD%. Simulation and experimental results are analyzed, compared and finally discussed.
