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

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

Small size and high density is the label of the modern high power DCDC supplies.Integrated magnetics technology is one of the efficient ways.How does it work?... View More

China created a term for electrical vehicles - new energy vehicles (NEV). I don't know how you feel, the first time I saw it, I just felt very strange. New energy?  There is no new energy. Energies (god created? who knows?) are all there in different forms, coming from different channels. Hu...... View More
