MOTOR CONTROLLER OF AIR CONDITIONER |
摘要 |
<p>A motor control device of an air-conditioner is provided to facilitate replacement by modularizing a converter and perform DC power supply conversion efficiently according to the capacity of an air-conditioner by replacing a converter module and a three phase bridge diode. A motor control device of an air-conditioner comprises: a plurality of switching elements for converters converting 3 phase AC power into DC power supply; and a converter(210) detachably modularized in order to be replaced with other modules. An inverter(220) comprises a plurality of switching element for the inverter to convert DC power into AC power having fixed frequency and supply the AC power to a three-phase electric motor. A converter microcomputer(240) and an inverter microcomputer(230) control the switching operation of the inverter and the converter.</p> |
