A power unit is provided which is capable of controlling electric current to be supplied to a load connected to the power unit, in a flexible manner in dependence on a load condition. Postive and negative converters of a cycloconver are connected to three-phase output windings of a three-phase generator and connected in an antiparallel manner to each other for generating a single-phase alternating current to be supplied to the load. A firing angle control device causes the positive and negative converters to be alternately switched to operate every half ...
[ What is claimed is:] [1.]1. A power unit comprising:a generator having three-phase output windings;a pair of variable control bridge circuits connected to said three-phase output windings of said generator and connected in an antiparallel manner to each other to form a cycloconverter for generating a single-phase alternating current to be supplied to a load;a bridge drive circuit for causing said variable control bridge circuits to be alternately switched to operate every half a repetition period of said single-phase alternating current, to thereby cau...
