For most closed-loop feedback control systems, phase margin is greater than 45° (less than 315°) when the loop gain is greater than 0 dB. Gain margin is -20 dB or lower when the loop phase delay ...

For most closed-loop feedback control systems, there are two basic rules: Phase margin is greater than 45° (less than 315°) when the loop gain is greater than 0dB. Gain margin is -20dB or lower ...

Again, it is important to make sure that the output voltage remains halfway between the two power supply voltages. This can be accomplished by adjusting V 2. Also, the power supplies remain constant.

It would be a masterpiece of understatement to suggest that control loop compensation holds much significance in power converter design. This is true in part because of increasing demand for ...
