SIMPLIS Technologies
Designing Digitally Controlled Systems with SIMPLIS
Christopher Bridge

A design methodology is presented for designing digitally controlled systems using the SystemDesigner features of the SIMPLIS simulator. Taking full advantage of these SystemDesigner capabilities, we demonstrate how users can simulate their digitally controlled systems such that they have the option, with a single schematic, to model the signal path as either signed integers or double precision floating-point numbers. Modeling the signal path with double precision allows users to take advantage of the SIMPLIS Periodic Operating Point and AC analyses. Modeling the signal path as signed integers captures the expected quantization effects of the digitally controlled loop.

This technique is applicable for both hardware and firmware/software digital control implementations. Using an LLC DC-DC converter as an example, we show how to transition from an analog controller to a digital control implementation.

Magsoft Cororation
Fast computation of Inductance, Capacitance, Current Density in conductor arrangements
Philippe Wendling

In power converters, the electromagnetic behavior of “metallic cabling” which interconnects semiconductor components is non-ideal : parasitic resistive, inductive and capacitive effects occur in such power devices causing respectively energy losses, switching overvoltages and EMC issues. In particular, interconnection parts (i.e. electrical conductors) generate electromagnetic stress and possibly system failures, since they add to the expected fonctional behavior of the converters.

This presentation will highlight the importance of 3D electromagnetic simulations which help designers in assessing these undesirable effects and improving system performances: InCa3D is a simulation software for low & medium frequencies dedicated to electrical interconnection modeling. Based on the innovative and very efficient PEEC (Partial Element Equivalent Circuit) method, it is well suited for analyzing the behavior (current distributions, radiated magnetic fields) of almost any kind of connections, additionally providing RLC extraction and generation of equivalent circuits.

Benefits of its use during the design of power devices will be illustrated by examples.

Ultra-high Fidelity Hardware-in-the-loop Simulation for Power Electronics and Microgrid
Alex Sedaghat, Applications Engineer, Typhoon HIL, Inc.

Significant and growing penetration of smart inverters represents both challenges and incipient opportunities to increase utility grid agility and stability. In addition to inherently fast dynamic control capabilities, these power electronics systems interact with increasingly diverse physical systems (such as renewable generation technologies) in complex ways. Indeed, grid is becoming a true cyberphysical system with a layered architecture comprising both power processing and control and communications. Classical tools that are used for simulation, testing, and system validation are very limited in both model fidelity and flexibility. In this talk we will present a new approach to power electronics and power system controls testing and validation based on ultra-high fidelity Hardware-in-the-Loop (HIL) real-time simulation.

Our HIL platform enables ultra-high-fidelity real-time simulation of power electronics converters, microgrids, distribution and transmission networks, with 1μs simulation time step. In addition, our HIL simulation is directly interfaced with real digital controllers, thereby eliminating modeling assumptions and thus providing the most realistic “flight simulator” experiences for power electronics and power system simulations. We will discuss how Typhoon HIL is changing the testing and quality assurance processes in power electronics industry today and how we are helping, in our small way, utilities and system integrators revolutionize the grid.

Accurate Modeling and Simulation of Contemporary Power Converters using Saber
Alan Courtay

Saber is a multi-domain system modeling and simulation platform that meets the challenges of contemporary power electronics verification. Saber combines robust mixed signal simulation with advanced modeling capabilities including power semiconductor and magnetic tools, state-flow and logic for control, and HDL and table look-up methods for efficient behavioral modeling. New Saber fault modeling and simulation enables functional safety and reliability verification of power electronics systems. Optimization-based algorithms identify the design parameters leading to optimal or worst-case performances, such as power efficiency. This presentation will showcase these features on a commercially available quasi-resonant flyback power converter.

Saber is particularly advantageous to model the control of power converters. The key features of the IC controller modeled in this flyback example are the frequency foldback and the input voltage feedforward function. A SPICE approach would not be able to easily model the blanking time of the frequency foldback function, which is a nonlinear curve conveniently created with the Saber Table Look Up modeling tool. Similarly, the MAST and VHDL-AMS hardware description languages offer a straightforward way to implement the expression for voltage feedforward without rigging up a subcircuit required by many other simulators.

Hitachi has introduced nHPD2 (next High Power Density Dual) as the next generation package standard for high voltage power modules. It has the benefits of low inductance, high power density and scalability, and also includes a current sensor and temperature sensor. This package not only targets the next generation of Si chip technology, but also brings significant advantages for use with SiC technology. In this seminar, we would like to introduce the state-of-the-art for Si and SiC in the nHPD2 form factor.

In addition to nHPD2, we have introduced the latest generation of 4.5kV IGBT for medium voltage drive applications, covering a wide frequency range. By using advanced trench HiGT (High conductivity IGBT), rated current was successfully increased by 25% realizing 1500A within the same footprint.

Cooling Fan Design System with Automated Performance Prediction

A cooling fan is widely used as a cooling device in electronics. In CFD, modeling methods of cooling fans can be categorized into two methods. One method is used to predict detailed flow by modeling the shape of the blade and the frame in detail. The other method is used to predict the flow rate as a simplified model defining the relation between the pressure and the flow rate (P-Q Curve). The former method is best suited for predicting performance of the fan itself while the latter method is suitable for an electronic system level simulation. While the latter method significantly simplifies the procedures of the electronic thermal simulation, it has still been challenging to utilize CFD for axial fans due to the complexity of modeling a fan in 3D, as well as the knowledge required to perform detailed fan simulations in CFD.

Therefore, we developed an innovative tool “”SmartBlades””, which allows a fan designer to quickly and easily design a fan in 3D and to predict its performance. SmartBlades is equipped with a sophisticated GUI which enables a user to intuitively design a blade profile by specifying parameters or dragging graph lines to define rake angles, skew angels, thickness, and other parameters of a blade. In this way, 3D geometry of a fan can be quickly and easily created even without any CAD experience. Furthermore, SmartBlades is linked to Cradle SC/Tetra CFD software and automatically performs the CFD simulation to report a fan performance curve including P-Q curve, power curve, and efficiency curve. As a result, the fan designer can quickly design an optimized axial fan to meet various criteria using SmartBlades and can significantly reduce the product lead time.
