Title:
AGING SYSTEM FOR POWER SOURCE UNIT
Document Type and Number:
Japanese Patent JPS58167974
Kind Code:
A
Abstract:
PURPOSE: To reduce the power consumption by connecting a power unit of a low power scale as load of a power unit of a high power scale successively.
CONSTITUTION: One power source unit PW2 to be aged is connected as load of a power unit PW1 with DC-AC inverter INV1 interposed. Another unit PW3 is connected to the power unit PW2 through an inverter INV2. Thus, the load DL is reduced to only one. When the efficiencies of the units PW1W3 are represented by η1Wη2, efficiencies of the inverter INV1 and 2, η1 and the output voltage and current VO3 and IO3, the AC input power VO3. IO3/η1.η2.η3. ηi2.
