Design and Development of a Totem Pole PFC Converter — A Simulation-Driven Approach
Dr. Anup Singh and Ullas Vishwakarma HS, Havells
This presentation explores a simulation-driven methodology for the design and development of a Totem Pole PFC converter, leveraging the capabilities of SIMBA to accelerate the engineering workflow from concept to hardware realization. It will detail the modelling strategies employed in SIMBA to accurately simulate the converter's behaviour under various operating conditions. Key design challenges such as control strategy implementation, dead-time management, and soft-start methodologies will be addressed, along with insights into how simulation helped optimize switching performance and thermal behaviour. The transition from simulation to hardware will also be covered.
Using SIMBA for Low Voltage Network Protection Study in Nuclear Installation
BATS Guillaume, Technicatome
Protective device coordination studies involve a lot of study cases, depending on:
- Power supply
- Network configuration
- Type of fault
- Fault localisation
In large networks, the number of study cases can exceed several thousands, which makes the task of identifying the “worst case” scenario quite tricky. Our purpose here is to use SIMBA’s ability to work with a Python interface to perform a large number of short-circuit studies in a low voltage network. Once all the study cases have been performed, the worst case scenario can be easily found.
The presentation will introduce the modelling of DC fuses based on experimental results, followed by the network study carried out with SIMBA through the Python interface.
Noise Augmented Feedback for Realistic Circuit Transient Simulation, Case Study for Single Phase Interleaved Totem Pole Inverter
Arief Noor Rahman, Power Control Design
Real-world circuits operate with various non-idealities. First are the non-idealities in the power loop circuit, i.e., parasitic components (parasitic resistance, capacitance, inductance). Non-linear inductance (saturation) and capacitance are some of the most common examples; these non-idealities are generally well understood and are commonly added to the simulation.
Second is measured noise on the circuit control loop feedback: (2a) picked-up noise in signal transmission and (2b) sensor self-generated noise. Noise (2a) generally does not affect the transient behaviour since it occurs at very high frequency and can be easily filtered out by using a simple low-pass filter (note: the filter must be fully modelled to ensure accurate transient response). Anyway, (2b) is more complicated since the noise characteristics are mostly either flicker noise or white noise, making such noise more difficult to filter.
Among the sensors commonly used for power converter feedback, the open-loop Hall-effect current sensor is known to be the noisiest and will be the focus of this presentation. For the case study, the interleaved totem pole inverter topology is selected since this topology is particularly sensitive to noise, especially for the low-frequency leg control. The following points will be discussed to help the audience understand the significance of noise modelling:
- Impact of the noise on the zero-crossing control of the interleaved totem pole inverter
- Physical Hall-effect-based current sensor noise characterization
- Noise modelling in the SIMBA environment
- Controller modification to mitigate the sensor noise issue
Simulation of a 130 kW Battery Charger for a UPS
Corentin Rizet, Sirepe
Multilevel converters make it possible to distribute stresses across higher-performing components while improving waveform quality. A 130 kW battery charger for UPS will be used to demonstrate this concept. Simulating these complex structures presents certain challenges, such as accounting for parasitic elements in the topology and accurately modelling the control system.
Residential Microgrid: From Theory to SIMBA Simulation and Experimentation
Ilhem Slama-Belkhodja, National Engineering School of Tunis
In many countries, small photovoltaic systems have developed more rapidly than large-scale renewable power plants due to the high cost and long implementation times of the latter, putting a strain on residential distribution networks (RDN). Distribution system operators (DSOs) have introduced limits to the amount of power that can be supplied to the RDN before the power quality deteriorates.
As a result, solutions are being explored to increase the photovoltaic hosting capacity of the RDN. These solutions involve controls integrated into IBRs (inverter-based resources), additional equipment such as BESS (battery energy storage systems) or PQID (power quality improvement devices), and concepts such as microgrids and collective self-consumption.
Studying these solutions requires simulation models that take into account the power converters and controls of all IBRs, as well as the characteristics of lines between consecutive generation and/or consumption points, sensing chains, and different types of load. The simulation must be fast enough for control developers, but without the complexity of dedicated network simulation tools such as EMTP-RV or digSilent.
In this context, we used SIMBA to simulate our experimental microgrid platform, employing average or detailed models depending on the scenario under study. The flexible, modular platform allows the integration of various commercial components or components developed using the PHIL (Power Hardware-in-the-Loop) approach. Several case studies can therefore be considered, highlighting the challenges associated with photovoltaic hosting capacity and the solutions implemented to improve it.
Leveraging SIMBA Cloud for Teaching – Isolated DC-DC Converters
Prof. Daniel Siemaszko, University of Applied Sciences and Arts of Western Switzerland
During lectures, tutorials, or conference presentations it is often useful to deliver live simulations in a web browser or to share interactive circuit links with the audience. This case study demonstrates how SIMBA Cloud enhances power electronics education by enabling students to explore isolated DC-DC converter topologies without installing software, bringing hands-on learning directly to the classroom or remote sessions.
