At first, the development and fundamental of monolithic switching power supply are presented in this thesis. then a novel monolithic switching power supply circuit only with four terminals is analyzed at detail. it uses pulse skip modulation and current - mode topology
論文研究了一種作為psoc原型電路的四端單片開關電源電路,此電路採用新型的跨周期調制模式,與傳統的脈寬調制模式相比,提高了輕負載下的工作效率;整體控制迴路採用電流峰值控制模式。Among them, phase shifted ( ps ) full bridge ( fb ) zero - voltage - switched ( zvs ) pulse - width - modulated ( pwm ) dc / dc converter has strong competitive power in big power capacity fields. but it has some limitations such as smaller load range with zvs and larger circulation energy. the ps - fb - zvs - pwm dc / dc converter with a saturable inductor utilizes saturable inductor s critical saturable current characteristic and storage energy, to enlarge load range with zvs and improve output efficiency under light load
其中,移相控制零電壓開關脈寬調制dc / dc全橋變換器在大容量領域很有競爭力,但它具有實現零電壓開關負載范圍小,循環能量大等限制,帶飽和電感的移相控制零電壓開關全橋變換器利用飽和電感的臨界飽和電流特性及儲能,來擴大零電壓開關( zvs )的負載范圍,提高輕載時的輸出效率,具有非常重要的研究價值。The switch power will operate at ccm condition when circuit is set to pwm mode. when pfm mode is selected for the operation mode, the switch power will still operate at pwm condition with the high load, the system will cancel the pwm mode and enter the pfm mode only when the load is drop to a certain threshold to boost the operation efficiency at light load, make the ic has high efficiency within wide load range
選擇pwm模式,開關電源將工作在ccm模式下;選擇pfm模式,在負載較高的情況下,開關電源仍然工作于pwm模式,只有當負載降低到一定程度時,開關電源才退出pwm模式,而按照pfm工作模式操作,跨過一部分時鐘周期,降低頻率相關功耗,以提高輕負載時低效率的問題,使得開關電源在很寬的負載范圍內都具有高效率。The second, the realization of the zvs has no concerned with the attribute of load. with the load of light or full, even the resistance or inductor load, the chopper can ensure that the main - switches will realize the zvs switching
其次,實現零電壓軟開關的條件與負載的性質和程度沒有關系,無論是電阻性負載還是大電感負載,無論是輕載還是滿載,都可以實現功率器件的零電壓開通和關斷。分享友人
