Abstract
Luo Converters which use voltage lift technique to provide high gain is a topic of research interest. They are used in motor drives, telecom, automotive applications and as radar and electronic warfare in military. In this work, mixed signal behaviour of constant frequency controlled PWM Ultra Lift Luo Converter is analyzed. The closed loop transfer function is derived using Perturbation theory, Sample-Hold theory and Modified Pade Approximation method. To get the margin of stability accurately, Slope Compensation is used. The expressions of the control current of the inner current loop of Converter with and without slope compensation are derived. Finally the controller is designed using PSIM 9.0 and SMARTCTRL 1.0 software and stability is analysed.
