Title:
電源装置
Document Type and Number:
Japanese Patent JP5467029
Kind Code:
B2
Abstract:
Provided is a power supply device, which can generate an alternating current voltage at a discretionary level from a power supply, such as a storage battery, and which can drive a power converting section, including even a time when starting up the power supply device and a time when the storage battery is being charged. A power supply device (100) is provided with: a power converting section (8), which has a storage battery (5) connected to the input side, and a load (7) or a commercial power supply (6) selectively connected to the output side, and which can bidirectionally convert power; a snubber circuit (9), which includes diodes (91a-91f), diodes (92a-92d), and a capacitor (93), charges the capacitor (93) by rectifying an output alternating current voltage by means of the diodes (91a-91f) and diodes (92a-92d), and absorbs a surge voltage generated when the power converting section (8) is operated; a main control power supply (31); and a diode (33), which selects a higher voltage out of a direct current voltage on the basis of the storage battery (5), and a direct current charged voltage charged in the capacitor (93), and which supplies the selected voltage to the main control power supply (31).
