This paper presents the novel load regulation technique for parallel connected POLs which reads for power supply on chip (power-SoC). In power-SoC, many POLs are implemented on the same chip. In this case, the conventional loop control (feedback control) may have some problem such as oscillation. The proposed strategy regulates the output voltage by changing number of the working POLs under fixed duty ratio. The parallel connected POLs system is implemented by means of MATLB/Simulink, and the operating characteristics are confirmed. In addition, the proposed control strategy is also verified experimentally.
