Control logic simulation for smps
WebThe modulator voltage gain Km, which is the gain from the control voltage to the switch voltage is defined as: RAMP IN m IN m V V K V F = ⋅ = Figure 2. Current-mode buck, linear model and frequency response. Current-Mode Linear Model For current-mode control, the ramp is created by monitoring the inductor current. This signal is WebSMPS are nonlinear, time varying systems, due to the switching actions. However, they can be modeled with an averaged small signal, linearized model, which is valid up to the power supply switching frequency f SW /2. Therefore, the linear control loop stability analysis using Nyquist and Bode plots can be applied.
