Abstract
A drive control device includes a self-excited generator to generate and output electric power by being driven by an internal combustion engine, and a separately excited generator to generate and output electric power by being driven by the internal combustion engine when the separately excited generator is in an excited state. The drive control device further includes a first power converter to convert electric power fed from the separately excited generator via primary terminals into DC power and output the DC power via secondary terminals or to convert DC power fed via the secondary terminals into electric power to be fed to the separately excited generator and output the electric power via the primary terminals, and a capacitor connected between the secondary terminals of the first power converter.
