Abstract
The APS control can be used to lessen the current force on switches see how to avoid load as the traditional interleaving control can be used to help keep better performance in heavy load. This paper looks into a manuscript pulse width modulation (PWM) plan for 2-phase interleaved boost ripper tools with current multiplier for fuel cell power system by mixing alternating phase shift (APS) control and traditional interleaving PWM control. To be able to reduce output fuel cell stack output current ripple or even the electricity/electricity ripper tools input current ripple, whether passive filter or active filter may be used, however, this will raise the complexity from the system. The boundary condition for swapping between APS and traditional interleaving PWM control comes. In line with the aforementioned analysis, a complete power range control mixing APS and traditional interleaving control is suggested. Loss breakdown analysis can also be given look around the efficiency from the ripper tools. Finally, it's verified by experimental results. The whole process of a switching cycle from the ripper tools could be split into six stages at boundary condition that the current force on switch is going to be bigger than 1 / 2 of the output current with traditional interleaving control
