Title:
ALTERNATING VOLTAGE GENERATION APPARATUS AND POWER OUTPUT APPARATUS
Document Type and Number:
WIPO Patent Application WO2006059748
Kind Code:
A3
Abstract:
A power output apparatus (100) includes first and second motor generators (MG1, MG2), first and second inverters (20, 30) and a relay circuit (40). The first and second motor generators (MG1, MG2) include first and second 3-phase coils (12, 14), respectively. The first inverter (20) alters periodically the potential at a first neutral point (N1) of the 3-phase coil (12). The second inverter (30) alters periodically the potential of the second neutral point (N2) of the second 3-phase coil (14) at phase corresponding to a phase-inverted version of the potential change of the first neutral point (N1). The relay circuit (40) responds to a control signal (CNTL) from the control device (60) to electrically connect first and second AC lines (ACL1, ACL2) to a connector (50), and provides an alternating voltage generated across the first and second neutral points (N1, N2) to the connector (50).
