A daasheet controlled multiphase DC-DC buck converter has been implemented in this thesis. Comparing to the single phase system, multiphase system has lower voltage ripple and better transient response. Also, in recent years, digitally controlled power converter becomes a hot research relying on its advantage. Therefore, this thesis focuses on how to achieve the multiphase converter by digitally.

k4105 The system uses voltage control to design and three mechanisms are added into the system, which are current balancing, adaptive voltage positioning AVP and auto phase shedding mechanism. Due to the nature of the multiphase structure, element value or impedance cannot be exactly the same between each phase in practice. By this reason, the current sharing between each phase becomes an important issue.

In this thesis, the current balance control is achieved by capturing and comparing the current between each phase, and adjusting the duty cycle. In addition, AVP mechanism can be implemented without the need for sensing or sampling the load current condition. This control architecture utilizes the error signal of the digitalized controller to obtain the current information.

Moreover, the phase shedding control can promote the efficiency by shutting down one phase. Experimental results show that all the mechanisms were achieved. Lee, “A classification and evaluation of paralleling methods for power supply modules,” in Proc.
