The following circuit is designed with a DCDC input voltage of 11V--15V and an output of 12V 1A
But now the output voltage is equal to the input voltage
What's going on? Can you guys analyze it for me...
After the square wave passes through an integrating circuit, the amplitude of the triangular wave will change with the frequency of the square wave. So how can we keep the amplitude of the triangular ...
