本論文主旨係利用數位信號處理器與類比控制器，以混合式控制之方式實現多相式低電壓大電流電源並聯模組。電源模組之架構為電流饋入推挽式降壓轉換器，前級為降壓式轉換器，而後級為推挽式轉換器，適合應用於低電壓大電流輸出之負載。並以德州儀器之DSP晶片TMS320LF2407A實現此並聯模組間之均流控制及多相式控制；以類比控制器實現ORing控制與脈寬調變控制，達到電路之高頻操作與系統保護功能。最後實作三組電源轉換器並聯，並可達到穩壓、均流、多相式與ORing控制。

In this thesis, the digital and analog hybrid control of multiphase power modules with low output voltage and high output current is studied and implemented. The topology of power module is a current-fed push-pull converter, the front stage is a buck converter and the rear stage is a push-pull converter, which is suitable for low-voltage high-current output. In order to achieve good flexibility, current-balancing control and multiphase control are realized with TI DSP TMS320LF2407A. ORing control and PWM control are accomplished with analog controller to achieve high frequency and system protection. Finally, three power modules are paralleled with phase-shifted control. The output voltage regulation, current-balancing, multiphase control and ORing control are accomplished in this system.
