要約(日本語): The instantaneous following PWM control technique is pulsed non-linear dynamic control method. This new control technique using analog integrator is proposed to control the duty ratio D of dc-dc converter. In this control technique, the duty ratio of a switch is exactly equal to or proportional to the control reference in the steady state or in a transient. Proposed control method compensates power source perturbation in one switching cycle and the average value of the dynamic reference in one switching cycle. There is no steady state error or dynamic error between the control reference and the average value of the switched variable. Experiments with the 3phase inverter that is smoothing capacitor-less have demonstrated the robustness of the control method and verified theoretical prediction. The control technique is very general and applicable to all type PWM converters.
