Title:
ELECTRIC VACUUM CLEANER
Document Type and Number:
WIPO Patent Application WO/2018/025344
Kind Code:
A1
Abstract:
In the present invention, a control device (5) computes a first power loss that results in an electric vacuum cleaner when a boost operation is selected to drive an AC motor (4) and a second power loss that results in the electric vacuum cleaner when a non-boost operation is selected to drive the AC motor (4). When the first power loss is greater than the second power loss, the control device (5) controls a boost converter (2) and an inverter (3) such that the non-boost operation is implemented to drive the AC motor (4). When the first power loss is smaller than the second power loss, the control device (5) controls the boost converter (2) and the inverter (3) such that the boost operation is implemented to drive the AC motor (4).
