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.
In this paper, we propose a concept of Field Programmable Power supply Array (FPPA), which is a fully digital controlled power supply, based on power supply on chip technology. The FPPA realize multi input voltage and multi output voltage only rewrite digital code of FPGA or DSP.
A power supply on chip (SoC) has been attracted attentions of many researchers because it can realize ultimate minimization of the power supply. It is quite promising for ICT applications because its features, such as smaller volume, high frequency response, and so on, fit for requirement of POL used in ICT equipment. In this paper, we propose the novel concept of digitally controlled multiple output...
Recently, the performance of the DSP and FPGA is developed remarkably. So, fully digital control is enabled in switch mode power supplies. However, in many cases, the control system is built by very complicatedly and very difficult theories such as the adaptive control, predictive control, and so on. Furthermore, in most popular PID control, its design method of the parameters is not clear, so derivation...
