摘要： The present invention discloses a double-edge pulse width modulation (PWM) controller based on the output current and output voltage which is modulated in real time by the output current and the output voltage. The controller uses an extra first adder to sum up the compensation signal and a triangular signal (or a saw-tooth signal); a second adder to sum up the output current signal to a bias value; a PWM comparator, with its non-inverting input receiving the output of said first adder, its inverting input receiving the output of said second adder and outputs the PWM signal.
摘要翻译： 本发明公开了一种基于由输出电流和输出电压实时调制的输出电流和输出电压的双边缘脉宽调制（PWM）控制器。 控制器使用额外的第一加法器来对补偿信号和三角形信号（或锯齿信号）求和; 第二加法器，将输出电流信号与偏置值相加; PWM比较器，其非反相输入接收所述第一加法器的输出，其反相输入接收所述第二加法器的输出并输出PWM信号。
