Title:
POWER CONVERTER AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/088294
Kind Code:
A1
Abstract:
In a power converter (105), the inductance L ([H]) of a reactor (121) and the capacity C ([F]) of a capacitor (122) satisfy condition (1). Furthermore, the power converter (105) eliminates the need for a current-limiting circuit between an AC power supply (102) and the capacitor (122). Here, αm ([A·s]) represents the value of the ratio of the maximum rated current squared time to the maximum rated output current of a diode, Pmax ([W]) represents the maximum power consumption of a motor, Vac ([V]) represents the voltage value of a three-phase AC voltage, and the value of constant a is 4.3.
