摘要
数字脉宽调制信号可以实现电源的数字控制。数字电源具有软件配置、自动电压/电流控制以及集群控制等优点。UCD系列芯片可以提供全套的数字电源实现方案,该系列芯片包括数字脉宽波形控制芯片、电源驱动转换芯片以及复位和时延控制芯片。本文基于以上套片研制出数字电源系统,给出了硬件设计图和软件配置方法,最后给出系统运行图。该系统可以应用于嵌入式高性能电子设备中。
Digital PWM signal can realize digital control of power system. Digital power has advantages such as software configuration, automatic voltage/current control, cluster control and so on. UCD series chips can provide complete turnkey solutions of digital power system. These chips include digital PWM control chips, power driver conversation chips and reset ＆ delay control chips. This paper studies the design method based on these chips. The hardware design and SOftware configuration method are introduced. The system can be applied to embedded high performance electronic equipments.
