“…Advantages and disadvantages of both solutions have been presented in Huang et al . A line transformer, which is typically made of an iron alloy, is large, heavy and expensive, but it allows for the increase of the DC input voltage without additional converters, isolates the DC voltage and filters HF noise generated by pulse width modulation (PWM) operation.…”

SUMMARYThis paper presents two algorithms for the creation of an analytical model of a single-phase transformerbased inverter, using either the measurements of the control frequency-dependent characteristics of the inverter or the initial in-circuit frequency-dependent measurements of the transformer. The paper discusses how the parameters of the line transformer influence the dynamic properties of the inverter and, as a consequence, the design of the instantaneous control feedback loop. Line transformers, widely used in industry, have not yet been analysed for use at higher than normal operating frequencies. The basic parameters of the transformer are the nonlinear functions of the primary voltage amplitude and frequency. The paper includes verification of both methods using the breadboard experimental model. In the final step, the inverter control transfer functions are calculated. To show the utility of both models, an exemplary discrete controller for the experimental inverter model has been designed and tested.

“…Other controllers generally used in rapid prototyping are based on microcontrollers and DSPs. However, these controllers are not suitable for the high performance ASIC controller for power electronics applications [24][25][26]. The main advantages of the FPGA-based XSG HIL simulation are (i) it provides a functional test of the FPGA as controller before connecting it to the actual system, (ii) sample delay effect of the digital controller can be tested, (iii) realisation of lags involved in interface of analogue variables and (iv) reduces the controller development time owing to HDL co-simulation tool.…”

The aim of this study is to develop a research platform for rapid prototyping of the power electronics converters for solar photovoltaic (PV) system applications. This study describes the field-programmable gate array (FPGA)-based hardware-inthe-loop (HIL) simulation of voltage source inverter (VSI) used for PV system power conversion. The PV system and inverter models are realised in simulation as part of the HIL to test the real-time functionality of the FPGA controller. The generation of switching control signals for the VSI and its interface with the PV system is developed through the Xilinx System Generator (XSG) domain. The XSG automatically generates the VHSIC hardware description language (VHDL) code using hardware description language co-simulation for generation of gating signal for modulation of the VSI. To validate the proposed approach, the sinusoidal pulse-width modulation using bipolar and unipolar switching schemes and current control method have been tested for the PV supported VSI. The proposed approach of the rapid prototype model has been designed and implemented in the laboratory through XSG and MATLAB/SIMULINK interface. Performance comparison between the software simulation and real-time HIL simulation has been demonstrated.
