Abstract
Input-series and output-parallel (ISOP) systems are very suitable for high input voltage and high power applications. Input voltage sharing (IVS) and output current sharing (OCS) of the constituent modules in the ISOP systems should be ensured. This chapter reveals the failure mechanism of IVS of the ISOP systems under extreme load conditions. Based on the existed IVS control strategies, this chapter proposes two methods, including changing the weighted averages of IVS loops and adding an IVS auxiliary circuit, to achieve IVS of the modules under the extreme load conditions. The experimental results are presented to verify the effectiveness of the proposed methods.
