ocw.mit.edudeal with damped oscillation and the important physical phenomenon of resonance in single oscillators. 1. We set up and solve (using complex exponentials) the equation of motion for a damped harmonic oscillator in the overdamped, underdamped and critically damped regions. 2.
Understanding and Applying Current-Mode Control Theory
www.ti.comFigure 3. Peak current-mode sub-harmonic oscillation. For D<0.5, sub-harmonic oscillation is damped. For D>0.5, sub-harmonic oscillation builds with insufficient slope compensation. By adding a compensating ramp equal to the down-slope of the inductor current, any tendency toward sub-harmonic oscillation is damped within one switching cycle.
