Title:
CONTROL DEVICE AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2017/200027
Kind Code:
A1
Abstract:
The objective of the present invention is to reduce costs relating to a CPU and to reduce the surface area occupied by a circuit board. This control device is provided with: rectifier circuits (12, 21) which convert a three-phase alternating-current voltage from an alternating-current power supply (11) into a direct current voltage; an inverter (13); smoothing capacitors (14, 24); an inverter power supply circuit (22a) which generates a power supply voltage for the inverter (13) from the direct current voltage output from the rectifier circuit (21); a CPU (23) equipped with a compressor motor (M1) control function and an auxiliary equipment control function; a CPU power supply circuit (22b) which generates a power supply voltage for the CPU (23) from the direct current voltage output from the rectifier circuit (21); a first diode (26) which is provided in a positive electrode wire (C(+)) connecting a direct current positive electrode bus bar (A(+)) and a direct current positive electrode bus bar (B(+)); and a second diode (27) provided in a negative electrode wire (C(-)) connecting a direct current negative electrode bus bar (A(-)) and a direct current negative electrode bus bar (B(-)).
