Title:
直流電源装置および空気調和機
Document Type and Number:
Japanese Patent JP6712104
Kind Code:
B2
Abstract:
The present invention realizes a small and inexpensive DC power supply unit and an air conditioner. The air conditioner comprises an electric impedance device (L1) connected to an AC power source (VS); a rectifier circuit (10) which converts an AC voltage (vs) when a switch of a short circuit reactor (L1) is appropriately connected to an AC power supply (VS) ) converted into a DC voltage (Vd) and applied to the load (H); and a control unit (M) that adjusts the amount of load between the load corresponding to the load (H) and the predetermined amount As a result of the comparison, a partial operation mode, that is, a partial switching mode and a switch of 80 or more times during a half cycle of the AC voltage (vs) are selected to be performed one or more times or more of the switching voltage (vs). The second operation mode is the operation mode of one of the high-speed switching modes, and the inductance value of the reactor (L1) is 3 mH or more and 6 mH or less.
