Welcome to SCAT K492.
K492 is a simulator application of SCAT (Switching Converter Analysis Tool) software for switching power converters. SCAT employs definitely original algorithms developed in EEL (Energy Electronics Laboratory) , SOJO University, Japan. SCAT is newly developed and does not at all depend on any other existing software such as SPICE. K492 is the simulator which satisfies all requirements for a simulator, such as accuracy, speed, stability, functionality and easiness.

 

 

Programmable Device
A programmable element of SCAT can describe arbitrary operation by the grammatical construction that looks like C language well. It is possible to correspond also to the simulation of digital, the analog coexistence circuit, and the DSP control circuit widely by three kinds of programmable elements of the voltage source, the computing unit, and the control machine.
Fast Analysis Algorithm
Algorithm of SCAT is developed and perfectly optimized for Switching Power Supply.. Thanks to this Algorithm, Very fast Simulation Speed has been realized ; Much faster by more than one hundred times faster than SPICE etc. which is designed for general purpose. No more wasting time as before. It suits for Cut and Try of Switching Power Supplies.
Low Cost and High Performance
It is unbelievably Low Price if compare with any of existing Simulation Software. And High Performance. Try Scat first before purchase a Simulator which may cost Tens of thousands of Dollars.
Object Oriented
One of the Features of SCAT is that it is made by Object Oriented Programming. So Easy to accept Customer's Feed back .Actually SCAT is enhanced continuously.

 

Digital control analysis by DSP
The DSP program can be created by block drawings. Each block contains simple function and microprogram is written inside which shows its function. Standard microprograms are supplied as library. Whole program is automatically generated by the block drawings and easily analyzed by the analytical function of K.492 as similar to ordinary simulation function.
Steady Analysis
Steady Analysis is the one of the most difficult to execute fast among Simulator for general purpose. SCAT can execute such Steady Analysis very fast.
Sweep Analysis
Sweep Analysis is a Characteristic Analysis when you vary a parameter such as Load. SCAT supports most of Parameters besides Load for Sweep Analysis and do it very fast. SCAT can complete in a few minutes ,while other Simulator requires a couple of HOURS.
Waveform Analysis
SCAT has a Powerful Oscilloscope Function made by Object oriented Programming. This allows you to scope current and voltage Waveform as if you were in a laboratory.
Transient Analysis
SCAT is good at analyzing Transient Response. You can display response waveform of Voltage and Current and their Trace of Max. and Min. Values during the one cycle as well. And if you combine it with Waveform Analysis or Continuous Analysis, you can get the Waveform of Transient Response on arbitrary point. This flexible Feature is unique to SCAT ,none of other software can hardly do it.
Analysis with Control Circuit
Fast previous Analysis can be done even if it contains control circuits. While existing Simulators can hardly analyze circuit when it is under control., SCAT can simulate even it is under control by PWM Control ,Switching Frequency Control because SCAT is optimized for Switching Power Supply Analysis only. SCAT has Control Verify function and accept Multi Loop to control plural items.
AC Input Analysis&3-Phase Input Analysis
SCAT can analyze AC Input and this factions make it possible to Ripple-Noise analysis or Power Factor Analysis. You can analyze both three phase circuit and Active filter Circuit even it is under control.
FFT and Harmonic Analysis
Harmonic Analysis will be "must" in near future,. Power Factor is an indispensable Test item. In SCAT's FFT window , FFT Analysis can be made arbitrarily by one click operation. And Necessary Functions such as Classification of harmonics regulation ,Power Factor of Input Current and Harmonic Distortion are supported in SCAT.
Frequency Response Analysis
K492 can analyze a frequency response which is important to confirm the stability of circuits. In K492, it is not required to make an average circuit model unlike in SPICE. K492 executes the analysis directly from the original switching circuit model.
Script analysis
The whole simulation can be automated by using script language.
Digital control analysis by programming element
The digital control can be analyzed by program when programming elements are used.
