DCI Inverter electronics for motor control in HVAC systems
Sinartis, has a very good experience in designing inverter boards for motor control (AC, DC, BLDC, PMSM, Stepper etc.)
We have done several applications in HVAC (Heat Ventilation Air Conditioning) systems for compressors and fans control in different power range from 1.5KW to 5KW with both single-phase 230 VAC and three-phase 380 VAC.
The control algorithm used is the sensor-less FOC (Field Oriented Control) with sinusoidal currents. The boards can accept several sensors of temperature, pressure, humidity etc.
