The staggered parallelBoostconverter combined with the currentmode control mode can notonly realize the currentflow between the phases, butalso reduce the current stress of the device. This article systematically introduces the working principle ofBoostunderthe staggered parallelstructure, adopts the valley currentmode controlstrategy of adaptive conduction time control, and adopts type IIcompensation to accelerate the response time ofthe system. Based on Simplis, a model was built and simulated, and the feasibility of this control method was demonstrated through software simulation. Wehavedesigned and developed a miniaturepowermodulethatincludestwoBoostcircuits, each of which can operate independently oroperate in interleaved parallel mode. The power module is small, lightweight, and has a smallrange ofoutput voltage fluctuations due to its control strategy and switch tube integration inside the chip. The peak conversion efficiency can reach 90%.
