Development of the inverter technique for air conditioners.

[In Japanese. / En japonais.]

Author(s) : TAKAKURA Y., MURAYAMA K., ITO M., et al.

Summary

In order to reduce the energy used by air conditioners, a permanent magnet synchronous motor is used and the drive system has been changed to a sinusoidal motor current drive. The authors have developed 3 inverter systems of position sensorless system, current sensorless system, and position/current sensorless system using the vector control theory. To achieve compactness and to reduce the cost, they developed a power module which includes converter and inverter devices, control circuits, etc.
