Abstract: This paper proposes an alternate configuration for digitally controlled parallel connected DC–DC power converters. Unlike conventional scheme which uses only one digital controller to control all of the n parallel connected power converters, the proposed scheme employs n digital controllers for n paralleled power converters. This arrangement prevents single controller breakdown from faulting the whole converter system, and therefore the reliability of the entire system is significantly improved. Furthermore, the configuration also fixates the computation resources allocated to each converter, regardless of the number of converter units employed. Experimental results suggested that the digitally controlled power converters function sufficiently in regulating the current distribution level under this configuration.
