Abstract
Method for operating a converter circuit with voltage boosting with N half-bridges, which in each case can be connected by their center connection to a phase of an N-phase generator and at an end side are connected in parallel with a series circuit formed by two capacitances, wherein each half-bridge contains a Top switch and a Bot switch, in which, in a PWM method with a fixed period duration at the beginning of the period duration, all the TOP switches are simultaneously switched on for the duration of a TOP switched-on interval. After half the period duration all the BOT switches are simultaneously switched on for the duration of a BOT switched-on interval wherein the TOP switched-on interval, and the BOT switched-on interval amount at most to half the duration of the period.
