Modeling Digital Control With SIMPLIS (Including Verilog HDL)
Recorded on 07-21-2016 The webinar starts with the digital hardware approach to modeling, where adders, multipliers, and other digital hardware models are used to implement the control algorithm. The second approach uses discrete time filters, which emulate the digital hardware model but with the benefit of allowing an AC analysis to be performed on the control loop. Next, SystemDesigner, which is a set of built-in modelling blocks which allow the user to use a single schematic to implement both a digital hardware and a discrete time filter model. Finally, co-simulating SIMPLIS with the controller implemented in Verilog HDL is covered. |

How SIMPLIS Periodic Operating Point (POP) Works
Recorded on 04-28-2016 The SIMPLIS POP analysis finds the periodic steady-state operating point of a circuit and is one of the most powerful features of SIMPLIS. To find the steady-state operating point, POP runs a sequence of transient simulations on your circuit, constantly refining the initial conditions between simulations. This one hour webinar will cover how to setup the POP analysis on a DC/DC converter, the core POP process, analysis parameters and common POP errors. |

All About Measurements
Recorded on 03-16-2017 SIMetrix/SIMPLIS has a powerful built-in measurement system which allows users to make measurements on simulation waveforms. As powerful as this system is, it is infrequently used. In this one hour webinar you will learn how to make measurements, and most importantly, add your own custom measurements to the program. |
Running AC Analyses On PFC Converters
Recorded on 11-17-2016 Running AC analyses on PFC converters has always been challenging because the circuit has no true steady-state when the input voltage is sinusoidal. The SIMPLIS POP and AC analyses assume the converter has a single operating frequency, namely the switching frequency. As soon as the sinusoidal input voltage is applied to the converter, running a POP analysis becomes difficult, but as you will see, not impossible. Tricks for running a POP and AC analysis on a PFC converter with an AC input voltage will be discussed and the loop gain results obtained with a DC input will be compared to the loop gain results when the converter is operating with an AC input. |

First Look - SIMPLIS Magnetic Design Module
Recorded on 03-26-2020 Magnetic devices have a large impact on power supply performance. Using the SIMPLIS Magnetics Design Module (MDM), you can design, simulate, and optimize your magnetic devices - inductors and transformers - as you concurrently design and simulate your power supply circuit in SIMetrix/SIMPLIS. SIMPLIS MDM allows you to build a physical model of an inductor or transformer by picking a core made of a specific magnetic material, wire, bobbin, and defining how the winding(s) are arranged. From this physical model, an electrical model is extracted to be used in a SIMPLIS schematic for simulation. The schematic simulation waveforms are then used by MDM to calculate losses and temperatures in the magnetic device. These results are presented in a detailed report, allowing insights into how the design can potentially be improved. This video presents an overview of SIMPLIS MDM and demonstrates its use using the example of an isolated 600 W, 380 V to 12 V DC-DC LLC converter. |

SIMPLIS Magnetics Design Module - Application: LLC Design
Recorded on 10-15-2020 This webinar will show how the Magnetics Design Module (MDM) can be used in the context of a real-world LLC converter design example. It will start by going through part of the design process of an actually manufactured 600W DC-DC LLC converter board, using MDM to demonstrate the advantages of the final design choices compared to the initial design. Further possible variations of the designs of the resonant inductor and transformer of the LLC converter will then be explored, along with their impact on converter performance. Trade-offs, such as cost vs. efficiency, will be examined. It will be shown how even in situations where the “right” magnetics design seems apparent from the application constraints and designer experience, MDM can be used to quickly evaluate many alternatives and “what ifs” straightforwardly and quickly, giving immediate insight into the impact of different design choices not only on the magnetics, but on the whole system. Abstract: Information on the application example that will be covered:
