Abstract :
The power supply system which requires the low-voltage/high-current output has been changing from conventional centralized power system to distributed power system. The distributed power system consists of bus converter and POL. The most important factor is the system stability in bus architecture design. The overlap between the output impedance of bus converter and input impedance of POL causes system instability, and it has been an actual problem. Increasing the bus capacitor, system stability can be reduced easily. However, due to the limited space on the system board, increasing of bus capacitors is impractical. The urgent solution of the issue is desired strongly. This paper investigates the system stability by means of bus converter with peak current mode control to eliminate the output impedance peak. As a result, this system has sufficient stability margin due to the output impedance peak disappeared by means of peak current mode control
