This new Volume 4 includes in one location the exposition of Condition-space Averaging Method and also the Cuk ripper tools as described in December 1976 doctoral thesis of Prof. Cuk. The Cuk ripper tools, invented on April 1, 1975, would be a prime motivator for growth and development of this general analysis and synthesis method. Professor Middlebrook lamented almost 30 years ago: “… When the models for those such converters are identical, it ought to be easy to derive this excellent model without getting to specify ahead of time any particular ripper tools. This issue was solved in an exceedingly elegant manner by Slobodan Cuk. In the 1976 PhD thesis he introduced case study approach to Condition-Space Averaging, which in one stroke eliminates the switching process from consideration and exposes the preferred dynamic response. Out of this model came exactly the same unique small signal equivalent circuit model, that is now known as the canonical model. Again using the clearness of insight, the type of the model becomes “obvious”: it has the 3 essential qualities associated with a Electricity to Electricity ripper tools, namely Electricity conversion, low pass filter and conversion ratio adjustment with a control signal.” Also incorporated within this new volume 4 are three key US patents describing not just fundamental Cuk ripper tools and it is Isolated Cuk ripper tools extensions, but additionally new general magnetics concepts: Coupled-Inductor and Integrated Magnetics. They are shown to be equally advantageous for brand new switching methods and novel topologies invented lately by Dr. Cuk. After 4 decades since its development, the enclosed description still continues to be probably the most authoritative description. Subsequent Circuit Averaging modifications unsuccessful to warrant the claim of “better insight” into ripper tools models and Switch Averaged models unsuccessful to verify the simplicity claim.
Both “methods” aren’t even competent to model simple extensions for example inclusion of a current clamp not to mention more complicated topologies for example essentially new topologies with three switches only, introduced by Dr. Cuk lately. The use of the Condition-space Averaging method also speeds-up naturally 1000 occasions switching ripper tools simulations and eliminates the natural convergence and precision problems of present simulation methods.
