Document Type and Number:
Japanese Patent JP2016192844
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To brake a fan motor over a long period when a power supply is turned off.SOLUTION: A motor drive control device comprises: an inverter circuit (16) that has a plurality of switching elements (Q1-Q6) for switching an input voltage (Vin) supplied from a power supply (2), and that outputs a drive signal to a motor (20); a gate driver (12) connected with the inverter circuit (16), and that on/off-controls the plurality of switching elements (Q1-Q6) on the basis of supplied first control signals (UH, UL, VH, VL, WH, WL); a regeneration voltage generation circuit (14) connected with the inverter circuit (16), and that on/off-controls at least some of the plurality of switching elements (Q1-Q6) so that a regeneration voltage to the power supply (2) is generated, on the basis of a supplied second control signal (BR); and a pre-driver (10) that outputs at least one of the first control signals and the second control signal.SELECTED DRAWING: Figure 1
