摘要： A computer power system with a keyboard, a computer housing, and a single AC to DC power converter that generates a DC power signal as long as it is energized by an AC power source. The power system is digitally controllable by the central processing unit (CPU) or from soft on/off switches on the keyboard and computer housing. This is made possible by a soft on/off controller that receives soft on/off control signals from the CPU and the soft on/off switches and in response generates a power transition signal that triggers shaping circuits to connect (soft on) or disconnect (soft off) power system output lines and power lines from the converter. The shaping circuits also ensure that the rising edge of a digitally switched power system output signal resembles the rising edge of the converter's cold-start power signal. Following a soft off event, the power system is in a low power standby state as power is not being supplied to the computer's power hungry components even though the converter is still generating a power signal.

摘要翻译： 计算机电源系统，带有键盘，计算机外壳和一个交流 - 直流电源转换器，只要交流电源通电，就会产生直流电源信号。 电源系统可通过中央处理单元（CPU）或键盘和计算机机箱上的软启动/关闭开关进行数字控制。 这是通过一个软启动/关闭控制器实现的，软启动/关闭控制器接收来自CPU和软启动/关闭开关的软启动/关闭控制信号，并作为响应产生触发整形电路连接（软启动）或断开 软关闭）电力系统输出线和来自转换器的电力线。 整形电路还确保数字开关电源系统输出信号的上升沿类似于转换器冷启动功率信号的上升沿。 发生软关断事件后，即使转换器仍在产生电源信号，电源系统仍处于低功耗待机状态，因为电源未供应给计算机的耗电组件。
