| Abstract: | Key technologies for novel switching power supplies are presented. By combining pulse skip modulation mode with current limit state machine, and introducing fuzzy control theory and chaos theory, characteristics of the novel switching power supply, such as energy transfer efficiency, transient response, load regulation rate and anti-interference, have been greatly improved. Low EM characteristics could be realized utilizing frequency jitter technique. With the rapid advancement of the semiconductor switching power device, novel switching power supplies will become shorter, smaller, lighter, safer and more cost-effective in the future, achieving both high efficiency and high quality. |
