DIRECT-TO-ALTERNATING CURRENT CONVERTER Russian patent published in 2000 - IPC

FIELD: electrical engineering, in particular, high-temperature space nuclear-power production equipment. SUBSTANCE: device may be used for heavy environment conditions, including vacuum, increased temperature, radiation and increased reliability requirements. Device has magnetic circuits and rotor, which has circuits of different magnetic conductance and is driven by drive. Each magnetic circuit has primary direct current winding and shared alternating current winding. Rotor circuits with different magnetic conductance are located between poles of each pair of poles of each magnetic circuit. When magnetic circuits are arranged in symmetry about rotor circumference, number of circuits with different conductance is proportional to l(p+l), where p is number of pole pairs of all magnetic circuits. Primary windings lead to excitation of magnetic excitation flow in different directions in gaps of magnetic circuits. Thus, alternating magnetic flow pulses are inducted in magnetic circuits and phase-shifted alternating electromotive force is induced in shared secondary winding. EFFECT: increased reliability. 2 dwg
