Abstract
A controlled rectifier inverter system of the type in which the inverter circuit has capacitors across which voltages are developed as a function of the current output of the inverter, such voltages being utilized to commutate the rectifiers of the inverter circuit, includes means to limit the magnitude of the rise in output current between successive commutations of the rectifiers of a group to prevent the achievement of a current in excess of that which can be commutated by the voltages on the capacitors.
