PSIM Testimonials

What our customers are saying about PSIM:

Richard Redl, Ph. D. - Consultant, ELFI S.A., Farvagny-le-Petit, Switzerland

"I started using PSIM in 1997. Over the years the program helped me in a great variety of power electronics design projects, including dc-dc converters, power-factor correctors, UPSs, standalone and grid-connected inverters, battery chargers, electronic ballasts, high-frequency automotive ignition systems, and advanced PWM control ICs. It became an indispensible tool that I am turning to on a daily basis.

For my work the most important benefits and features of PSIM are:

First of all, it is an excellent time-saving tool in product development because it eliminates the need for multiple hardware iterations. After verifying the design by PSIM, even the most complex power electronics systems tend to work right away as expected.
The built-in AC sweep tool carries out the frequency response analysis on the actual switchmode circuit and not on a simplified small-signal model. This makes it is easy to include the parasitics and other second-order effects, and eliminates the need for and tedium of developing the averaged model. It also allows investigating novel power converters whose frequency responses have not yet been determined analytically.
The program has a comprehensive library of generic power electronics components, signal sources, control blocks, and measurement functions. It is quick and easy to set up, simulate and probe even a very complicated system.
The powerful subcircuit feature and the wide range of combined components (RLC branches, transformers, single-phase and three-phase diode and thyristors bridges, etc.) keep the visual clutter on the computer screen at minimum.
The simulation is very fast, which allows exploring alternative design approaches and component sensitivities without spending a lot of time on waiting for the results. The outstanding processing speed of PSIM is also very useful in cases when both line-frequency and high-frequency components are present, e.g. power factor correctors or inverters.
Each revision of the program included practical time-saving suggestions from the users, including myself.

In general, PSIM is a flexible, easy-to-use and cost-effective software tool, optimally suited for power electronics simulations."

"We have been using the PSIM simulator since 2003, and today we are currently using multiple PSIM licenses in our Engineering Department.

Our company specializes in the design and manufacturing of High Voltage Power Supplies for medical applications from 2 to 180 kV and up to 120 kW. Once we included all stray and parasitic elements of our power supplies in the simulation environment, the PSIM simulation results were almost exactly the same as the measured results in the final product. Now we can predict performance with PSIM in our high frequency power supply designs and even test dynamic closed loop conditions without building engineering prototypes. The results are so accurate that we can go directly to preproduction with excellent success.

We also use SPICE simulator in some cases. However the simulation time with SPICE in our case is so long that SPICE simulation becomes unusable.

PSIM is extremely fast since non-linear elements are only used where we choose that they are important. Furthermore, the fact that PSIM separates power and control has a major effect on reducing simulation time. Another very useful feature is the ability to integrate DLL blocks into the circuit with the code that we wrote. This is of great help to emulate a software routine that would be used in a microcontroller used in our power supplies. We also use those DLL to emulate all our control logic to again reduce simulation time.

In summary, with PSIM, we can improve our power supply performance, increase reliability because we can do virtual testing beyond what we could do in the real life, and drastically reduce the time to market from design to the final product."

G. Pace - Principal Engineer, LTI Power Systems (formerly O.E.M. Inc.), Texas, U.S.A.

"OEM Power Systems (OEM) is a designer and manufacturer of power systems, such as AC and DC motors, drives, and generator controls, among others. Although it creates these systems primarily for the drilling industry, its other customers include companies from a diverse list, such as dredging, mining, energy and utility organizations.

OEM has used PSIM to improve its existing motor drives and control systems, and to develop new products. In addition, the company has used PSIM to investigate and explain specific problems experienced by its customers, and then to determine the effectiveness of proposed solutions as quickly as possible. OEM also uses PSIM to design components in its new systems, a step that has replaced considerable "trial and error" with "trial and success".

Recently, OEM used PSIM on an effort to simulate a power system on an offshore drilling rig. The simulation was designed to identify problems with high-frequency common mode currents in the power system, and to design filters to remove them.

OEM also simulated system harmonics (low- and high-frequency) in multiple drive systems, and designed active and passive filters to mitigate these effects. In addition, the organization used PSIM to simulate long cable impacts on a motor transient over voltage, and designed filters to mitigate this issue.

PSIM's ability to run at fast speed made it very effective in all of OEM's projects. Additionally, PSIM's built-in code framework, along with its vast library of components, improves the efficiency of the code OEM creates, saving significant development time. Moreover, the simulations it performs are measurably closer to actual implementations.

Because the tool is specifically aimed at power electronics and power systems, PSIM enabled OEM to run efficient, targeted simulations that matched its needs precisely. And when a poor simulation is worse than none at all, accuracy is critical."

"Great product! I have been using PSIM for many years to perform power electronics systems and circuit-level design.

The ease of circuit entry, the speed of processing circuits, and the flexibility to move between and join actual circuit elements and mathematical control models make PSIM an ideal tool for "what if?" work. While its power components are generic in nature (as opposed to the tediously specific implementations in some competing software), PSIM provides the capability to focus on the parameters of particular interest in a design.

The ability to integrate machines into the electronic simulation, along with the availability of multiple machine models, makes PSIM an exceptional tool for motor drive applications. Additionally, the wealth of transformer models, and the ability to work in both an analog and a digital domain for control, affords great flexibility in modern power circuit design, based largely on DSP control techniques.

Furthermore, its processing speed enables demonstration of "live" simulations with customers during design reviews, and allows for highlighting tradeoff effects "on the spot".

Overall, I have found that its speed of entry, robustness, and rapid processing make simulation in PSIM a very productive environment for design and development."
