peak current mode control in DC-DC switch mode power supply
Posted by zheng3726 5 Year ago
Peak current mode control is very popular in DCDC SMPS.It has many advantages,but it is susceptible to noise.When the duty cycle is greater than 0.5, it oscillates.This attached PDF explains the symptom in theory. Oscillation of PCM ... View More

Average current mode control in SMPS
Posted by zheng3726 5 Year ago
Current mode control as usually implemented in switching power supplies actually senses and controls peak inductor current. This gives rise to many serious problems, including poor noise immunity,a need for slope compensation, and peak-to-average current errors which the ...... View More
