Title:
POWER CONVERSION DEVICE AND METHOD, AND TRIANGULAR WAVE GENERATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2007/102601
Kind Code:
A1
Abstract:
Provided is a power conversion device for converting an AC power outputted from
a generator into a DC power for supply to a battery (load). The power conversion
device includes: a thyristor (switch unit) connected between an output unit
of the generator and the load; and a gate control unit (control unit) for generating
a triangular wave voltage corresponding to each cycle of the AC power outputted
from the generator, generating a differential voltage between the voltage supplied
to the load via the thyristor and a predetermined target voltage, and controlling
the conductive state of the thyristor according to the triangular wave voltage
and the differential voltage.
