“…The output voltage is not controlled, and it is not possible to impose the shape of the current wave. In this case the value of the output voltage depends on the value of the input voltage and the applied load, the current waveforms depend on the value applied to the inductive filter, in the case of applying a considerably high value to the input current of each phase it can assume a rectangular shape (considering only a half cycle) also due to the conduction of the diodes, which will conduct the electric current in a range of 30° and 150° [6][7][8][9]. In the case of Rectifier 2, it consists of three single-phase modules, each module consisting of an isolation HTR can be classified into two large groups, with HTR in series with the power flow and HTR in parallel with the power flow [1], as shown in Figure 1.…”

The unidirectional hybrid three-phase rectifier (UHTR) with Boost converter consists of two different rectifiers (Rectifier 1 and 2), where Rectifier 2 consists of modules corresponding to the phases. Each rectifier processes different part of the current waveform at the input, so that the sum of the current waveform parts is sinusoidal, or multilevel. Analyzing existing literature, the UHTR with Boost converter and isolation transformer, is proven as a classic solution with high weight, volume and cost. Therefore, in 2019 the UHTR with Boost converter was proposed, without any isolation transformer. To do this, it was necessary to replace the Boost inductor of each Rectifier 2 module with a coupled inductor. However, the proposed UHTR has not described the coupled inductor in details, neither the control circuit and the decoupling of the power circuit with the control circuit were described. Therefore, this main objective this paper is to provide answers to those aspects, and consequently present the UHTR proposal in a more realistic and practical application way, thus favoring the implementation of the prototype. A simulation of the proposed UHTR with coupled inductor was performed in the PSIM version 12.0 software with a power of 20 kW. The results of the proposed UHTR show that there is no current interaction and it works correctly, having a high PF of 99.92% and low total harmonic distortion of 3.96% at full load. In this way, it is proven that it is possible to implement an UHTR with a Boost converter and using coupled inductor.
