Title:
INVERTER DEVICE
Document Type and Number:
Japanese Patent JPS5944980
Kind Code:
A
Abstract:
PURPOSE:To reduce the harmonic of a power source side by connecting the first and second rectifiers to a smoothing condenser and differentiating the phases of the input voltages of the rectifiers at the prescribed angle. CONSTITUTION:A phase converter 50 which has a 3-phase transformer has the primary coils 51 which are connected to AC power sources R, S, T in a star shape, and the secondary coils 52 which are connected in a delta shape. The first rectifier 7 is connected to the power sources R, S, T, and the second rectifier 59 is connected to the secondary coil 52 if the phase converter 50. Accordingly, the phase of the input voltage of the second rectifier 59 is different from the phase of the input voltage of the first rectifier 7 by the prescribed angle.
