STUDY AND DEVELOPMENT OF TRANSISTORIZED MODULAR POWER CONVERTERS
Abstract
INVESTIGATIONS WERE CONTINUED ON THE FOLLOWING TOPICS: (1) methods of voltage regulation, (2) methods of voltage sensing, (3) methods of obtaining multiple output voltages, and (4) methods of obtaining multiple output power levels. At least 2 approaches in each topic were made with the advantages and disadvantages in the modular concept discussed. In voltage regulation methods, output regulation is compared to input regulation and multiple sensors for multiple output voltages are compared to a single sensor for multiple output voltages. In methods of obtaining multiple output voltages, different output transformers are compared to a single output transformer and in methods of obtaining mulitiple power output levels, separate power stages are compared to parallel power stages. A typical modular system is prese ted which illustrates the flexibility of the modular concept. A breakdown of the concept results in 19 basic modules to cover 2 input voltage ranges, delivering any power output up to 300 watts at 10 different output voltages, the output being either regulated or non-regulated. This results in a total of 188 different power supplies. (Author)
