Abstract

Inverter as one equipment relates closely to the renewable energy sector gain more and more important role in utilizing renewable energy widely. The inverter converts dc to ac form by a specific switching strategy. In this research, the switching strategy employed unipolar sinusoidal pulse width modulation (SPWM). The switching schemes were obtained by synthesis from sine lookup table that the width of pulses were obtained from simulation of PSIM. The aim of this research is to create a switching scheme in a software and then implemented in16-bit digital signal controller (DSC). Experiment in lab scale has been done to verify the proposed unipolar SPWM. The results showed that SPWM signals were easier generated in 16-bit digital signal controller (DSC). Other that, feature of PWM in this DSC has been supporting in inserting dead-time to avoid shoot through current at IGBT.

Abstract

Solid-state transformer (SST) could be a solution for a future distribution system, in which many renewable energy sources (RES) are integrated. The SST consists of a single-phase dual-active bridge (DAB) converter, which is scale-down the dc voltage level. The control objective of the DAB converter used in the SST is to control its output voltage. This control strategy consists of a proportional-integral (PI) controller and a single-phase shift (SPS) modulation. Numerous literatures have mentioned about the SPS modulation for the DAB converter. However, they do not provide procedures in implementing the SPS modulation in the real controller. This paper aims to develop the SPS modulation in the real controller of the STM32F446RE microcontroller. The proposed SPS modulation is based on a master-slave timer feature, which is available in the STM32 microcontroller. The development process and testing of the complete control strategy of the DAB converter were carried out in the hardware-in-the-loop (HIL) simulation using Typhoon HIL. This scheme speeds up the development of process and reduces the costs. The experiment in the HIL environment shows that proposed control strategy of the DAB converter consisting of the PI controller and the SPS modulation is successfully implemented in the real microcontroller of the STM32F446RE. The proposed control strategy of the DAB converter is capable of bidirectional power flow, which is useful for integrating distributed generators in the load side. Moreover, this control strategy can reject the disturbance caused by loads.
