Kaushik, Gaurav (2014) Compensator Design for DC-DC Buck Converte using Frequency Domain Specifications. MTech thesis.
In recent times integrated power management circuits have emerged as an important component of the portable application market. Designing a power supply for meeting high efficiency and good transient response has been a major topic for research in recent years. The DC- DC converter demands are increasing due to their small size, high efficiency and easy to use characteristics. In this study, we have studied few ways to design the controllers for the DC-DC converter which can control the ripple content of the system to achieve the required performance and good regulated voltage. The methods described can be implemented in hardware circuits very easily. The frequency domain specifications are used to tune the controllers as they have more effect on their performance and the calculations get simpler when working in frequency domain. These methods gives the exact values that can be directly used unlike the earlier used trial and error procedures. They are designed for the voltage mode controlled buck converter topology. Various controllers like PID, TYPE-III Controller and hardware simulation is done to verify the result.
