近年来,数字电源技术取得了巨大进步。在电源数字化方面走在前面的TI公司,已经用DSP的TMS320C28F10制成了通讯用的4 8V输出大功率电源模块。其中PFC和PWM部分完全为数字式控制。现在,TI公司已经研发出了多款数字式PWM控制芯片。目前主要是UCD7000系列,UCD8000系列和UCD9000系列,它们将成为下一代数字电源的探路者。从09年1 2期开始,本刊以连载的形式刊登由刘胜利高工编译的关于开关电源数字化新技术的IC产品系列讲座,供业内产品开发及使用该产品的工程技术人员参阅。
In recent years, digital power technology has made great progress. In front of the power digital company TI, DSP has been made with the communication TMS320C28F10 48V output power module. PFC and PWM part of which is completely digital control. Now, TI has developed a number of digital PWM control chip. Currently mainly UCD7000 series, UCD8000 series and UCD9000 series, they will become the next generation of digital power Pathfinder. From January 2009, the journal has published a series of IC product lecture series on switching power supply digitization technology compiled by Liu Shengli in the form of a series of articles for industrial product development and engineering and technical personnel who use the product.
