[DSP program] PWM模块原理及使用

Description: F28027有8路PWM（四个模块），4路HRPWM，特别对设计高精度电源提供了方便，每个PWM模块中又包括以下几个子模块：时基（Time-base）模块、计数比较（Counter-compare）模块、功能限定（Action-qualifier）模块、死区控制（Dead-band）模块、斩波（PWM-chopper）模块、事件触发（Event-trigger）模块、制动（Trip-zone）（不知道这样翻译恰当否）模块、数字比较（Digital Compare）模块。从这些模块的命名上看，用它来做个电源，是再恰当不过的了。(F28027 8 PWM (four, 4 HRPWM module), especially for the design of high precision power supply provides a convenient, but also includes the following modules: base in each PWM module (Time-base) module, count (Counter-compare) module, function limit (Action-qualifier) module, dead time control (Dead-band) module, chopper (PWM-chopper) module, event trigger module, brake (Event-trigger) (Trip-zone) (do not know whether proper translation) module and the digital comparison (Digital Compare) module.
