4 Analysis of Pulse-Fed Single-Input Single-Output Systems

The pulse-width modulation (PWM) technique using thyristors and gate turn-off thyristor (GTO) switches is a popular method for controlling output DC voltage/current from a fixed supply in a lossless manner. There are many schemes for attaining such control, encompassing numerous application areas such as traction, uninterruptible power supply (UPS), and voltage regulators [1,2]. The complexities of operation of such DC-to-DC converters are compounded by the nature of load that may be nonlinear in some cases. To have a complete knowledge of the circuits and to predict the performances of the devices, various analytical techniques are proposed with the basic objective to know the total ...
