Abstract:

In this paper, an analytical technique is presented for time domain analysis (transient and steady-state response) of perturbed PWM push-pull DC-DC converter using interesting corollary on Kharitonov’s theorem. The main advantage of the proposed analysis is that even though the transfer function model of a PWM push-pull DC-DC converter is perturbed, the complete analysis has been done on a linear transfer function model of a PWM push-pull DC-DC converter. The proposed analysis is verified using MATLAB simulation. This analysis will be very much useful to power electronics engineers, since the technique is very simple and computationally efficient and easily applicable in precise applications such as aerospace applications.
