Limitations of the magamp regulator and an improved magamp choke design procedure

Some inherent limitations of the magamp regulator are examined, and their effect on square-loop choke design is explained. One effect is that the commonly used area product design and method may not produce a core which will regulate properly. A core design procedure that includes these factors and utilizes the core volume as well as the area product for optimizing core size and core loss is developed. The impact of choke parameters on loop performance is demonstrated.<>
