Advanced Control Schemes for Voltage Regulators
… and high di/dt, otherwise, a lot of decoupling capacitors are necessary. Capacitors make the VR cost and size higher. Therefore, the VR control method is very important. This dissertation discusses the way to increase the speed of VR without degrading other functions, such as the system …

High Frequency, High Current Integrated Magnetics Design and Analysis
… di/dt, the VRM must use a higher number of capacitors to supply the transient energy. This is an undesirable solution because of the increased cost and real estate demands this would lead to in the future. Another solution to this problem is to increase the switching frequency and control …

High Frequency, High Current Density Voltage Regulators
… path to the processor, it needs sufficient capacitors to relay this energy. The capacitors' number appears to be unrealistically large if we follow today's approach for the future processors. High frequency VRM with high control bandwidth can solve this problem, however, the degradation of …

Modeling and Control Strategy for Capacitor Minimization of Modular Multilevel Converters
… design challenges in MMC is to reduce the capacitor size. In the current practice, a rather large capacitor bank is required to store line-frequency related circulating energy, even though a number of control strategies have been introduced to reduce the capacitor voltage ripples. In the …

Modeling and Control of Modular Multilevel Converter
… conversion applications. However, large module capacitors are usually required in MMCs to store large circulating power of line-frequency and its harmonics that flow through the capacitors. Even though several methods for minimizing the circulating power have been proposed in the literature, …
