Below are links to models I built but many were contributed by readers also.
The LTspice files for simulating the Vienna rectifier with dq0 are here while the examples for the variable toff Vienna are there.
The ZIP contains the LTspice files for simulating the LLC converter in current-mode control described in the presentation LLC Simulations in AC and TRAN.
This set of LTspice files will let you compensate and simulate BCM PFC operated in voltage-mode constant on-time control.
This is a set of LTspice compensators which automate components values calculations for type 1, 2 and 3 with an op-amp and type 1 and 2 with a TL431 and an OTA. The ZIP file is here.
I have recently simulated a dq0 3-phase PFC in both cycle-by-cycle and average modes. The SIMetrix version is availble in my ready-made templates but I have also simulated the entire project in LTspice. The PDF describing the PFC construction is here and the set of LTspice models is there.
The ZIP file for the ready-made templates for SIMPLIS is here, it is regularly updated.
If you want to run a double-pulse test in SIMetrix, this PDF explains how to import the SPICE model of your transistor (MOSFET, GaN or SiC). The SIMetrix file is here. This application note from Rohde & Schwarz is an interesting read on the measurement techniques for double-pulse testing.
PWM Switch LTspice: Mark Dimattina offers a way to implement the PWM CM version in LTspice. Thank you for sharing your models Mark. The documentation is here.
PWM Switch LTspice: Byron Rogers kindly shares his PWM Switch model also intended to be simulated in LTspice.
TL431 models discussion: an interesting discussion on the TL431 and the performance of several available models.
New LTspice models: Didier Balocco has come up with a new series of LTspice circuits implementing the PWM Switch model in voltage and current modes. There are plenty of examples plus a quick installation guide. The files are here. Merci Didier !
LTspice models (2008): Charles Denton has been kind enough to translate the PWM switch models in LTspice. Yes, it is obvious, you need a good book to understand how to use them... ;-)
It has been reported that parameter "K" could be mixed by LTspice with the Boltzman constant. To avoid this, please change "K" into "Kf" and it should work. Kindly pointed out by Dennis in March 2015.
VerilogA models: the PWM switch model working in VerilogA, nicely translated by Nico Cyr formerly with ON Semi.
VerilogA models: the PWM switch model working in VerilogA, a new model contributed by Rainer Krenzke from Dialog Semiconductor.
Flyback current-mode automated calculation spreadsheet: this is a new automated software which calculates the TL431 elements to stabilize of a flyback converter operated in peak current mode control. The software includes mode transition, sub harmonic poles and optocoupler pole contribution. Check it out!
These are models I built for the cookbook released in 2001:
Sam Ben-Yaakov models are based on the Switched Inductor Model (SIM) concept as described by this publication. The models offered are averaged models adapted in a .SUBCKT form and let you simulate the following topologies: BUCK, BOOST, BUCK-BOOST/FLYBACK, FORWARD, SEPIC in both Current-Mode (CM) and Voltage-Mode (VM) versions. As averaged models, they find their dc point alone and allow AC and TRANsient simulations. Please note that CM models do not predict subharmonic oscillations at Fsw/2 (PSpice, IsSpice). bullet
Ridley models are ac models only (PSpice, IsSpice). They can't compute their dc point alone and are therefore dedicated to ac simulations only. They correspond to an adaptation of original SPICE2 scripts where complex parameters needed to be calculated by the user. These models naturally shield you against these drawbacks and let you simulate the same topologies as above in a snap-shot. They nicely predict Fsw/2 oscillations. bullet
Sam Ben-Yaakov presented during PCIM 2001 some extensions to his original GSIM models. These new models now include various losses such as inductor ohmic losses, switch rDS(on), diode forward drop and dynamic resistance. These devices have been encapsulated into working subcircuits (current-mode and voltage-mode) and are available for both IsSpice4 and PSpice. bullet
Robert Erickson and Dragan Maksimovic, from CoPEC, have included a simulation portion in the second edition of their book, "Fundamentals of Power Electronics". These models were first presented during PESC 1999. I have adapted CCM-DCM1 and CCM-DCM2 to IsSpice4 because original versions were only PSpice compatible. The library contains the above models and a few zipped ready-to-use examples can be downloaded in ICAP/4 8.1 version (Flyback, Buck and Boost in voltage-mode only).
