摘要: This chapter presents an LLC resonant converter with constant frequency. Since converters possess the advantages of high efficiency and low electromagnetic interference, they are widely used in many applications. However, EMI filter design becomes more complex because variable-frequency operation converter. Therefore, this chapter, a circuit configuration buck cascade converter, buck-fed is proposed to complete constant-frequency simplify design. The applied as input source for In addition, by adjusting output voltage regulation can be achieved. Finally, prototype 380–400 V 24 V/10 A implemented. experimental results demonstrate feasibility
