PURPOSE: A line start permanent magnet motor(LSPM) driving driver is provided to increase the compressive efficiency of a refrigerator by sufficient satisfying an initial starting property under lower voltage and lower frequency states. CONSTITUTION: A switch driving part(600) controls the drive of a starting switch(100) and a driving switch(200). A power supplying part applies power to the switch driving part. A driving condenser(400) is in parallel connection with an auxiliary coil part. A driving condenser(300) is in connection with the driving condenser. The starting switch, the driving switch, and a constant temperature-based heat emitting element(700) are composed of triacs. |
