Title:
DRIVING DEVICE OF COMPRESSOR
Document Type and Number:
Japanese Patent JP3831852
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a driving device of a compressor which can reduce a stress due to switching of switching elements and also can lower the noise by dispersing a magnetic sound due to the switching on the occasion of preheating the compressor.
SOLUTION: A switching pattern of the switching elements 5-10 for sending a direct current at each prescribed time to each phase of a three-phase motor 2 in each prescribed period, and a switching pattern of the switching elements 5-10 for interrupting the current to each phase of the motor 2 at each prescribed time, are combined with each other and set in a microcomputer 11. Based on the combined switching patterns, the switching elements 5-10 of individual phases of an inverter circuit 4 are switched before the compressor 1 is started.
