This paper presents a digital hybrid ripple-based constant on-time control scheme for voltage regulator modules (VRMs). Due to the sampling effects of the digital implementation, the stability issue becomes worse than the analog ripple-based control schemes, especially when low-ESR decoupling capacitors are used as the output filter. In order to stabilize the system and to fulfill the output impedance...
This paper develops a new set of small signal models for buck and boost paralleled and interleaved converters. These models provide a more accurate representation of the small signal behavior of this class of converters by including independent duty cycle control of each paralleled interleaved converter in the model and taking into account the dumping effect from interleaving the converter stages...
This paper presents an analytical design method of indirect full digital controller with a simple structure for three-phase inverter system. Most of conventional researches on the analytical design of controller have been studied about the structure of continuous-time controller, and so the final implementation of full digital controller for industrial application was complicate and anyway based on...
