The purpose of this paper is to present the digital overcurrent detector for the peak current mode dc-dc converter which has been already applied to the server for the data center. The proposed peak current detection circuit is composed of the RC integrator and comparator as the A-D converter for the detected current. The proposed method can detect the overcurrent by using the RC integration time...
The data center of the cloud which supports the recent communications infrastructure requires the high reliable control systems in order to control its enormous electric power and exhaust heat. It is important to reduce the energy wasted by the control systems. The FPGA is watched because of the low energy, the long sustainability, and the simple architecture. It is clarified that the FPGA realizes...
We propose a multi input voltage and multiple output voltage DC-DC converter using H-bridge converter for power supply on chip. We analyzed the operation mode of the H-bridge converter and also propose the suitable operation mode for power supply on chip. The proposed POLs realize stable output voltage and high efficiency over the wide range through digital control.
To take advantage of volatile renewable energy, implementation of digital control is effective since it supports the application of various advanced control theory and communication functions. However, it is usually difficult to use the actual plant to be controlled at the control software development stage, particularly in terms of cost and safety. Therefore, during the control software development...
