HIGH-EFFICIENCY OUTPUT STABILIZATION POWER GENERATION DEVICE AND SMALL WATER-FLOW TYPE HYDRAULIC POWER GENERATION SYSTEM

摘要

A power generation device (10) is constituted by a permanent magnet type power generator (20), a control circuit (30), and an addition connection section (38), and applies an output voltage to a load (12). The permanent magnet type power generator (20) is a three-phase AC generator. Each output winding for the U-phase, V-phase, and W-phase has the number of windings reduced by half so that the output voltage is half of a rated voltage, and is constituted by mutually parallel two-system output windings (24U₁ and 24U₂, 24V₁ and 24V₂, and 24W₁ and 24W₂). The output voltages in the two-system output windings are rectified in the control circuit (30) for each U-phase, V-phase, and W-phase with each system maintained independently; stabilized by step-down DC to DC convertors (34-1, 34-2) for each system; serially added through the addition connection section (38); and then applied to the load (12).
