As a general guide:
Motor Driver ICs series | |
---|---|
ECN301*1 | Home air-conditioning, indoor fans, domestic boiler combustion fans, air purifies, bathroom dries, etc. |
ECN302*1 | Home air-conditioner outdoor fan. |
ECN306*2 | White Goods and package air-conditioner, automatic doors, etc. |
Gate Driver ICs series | |
---|---|
ECN303*3 | Pumps, dishwashers, etc. |
ECN305*4 | Washing machines, air-conditioner compressor, refrigerators, general purpose inverters, etc. |
Inverter Ics can be connected directly to a DC voltage supply. For example, in AC100V/AC200V, the voltage of DC141V/DC282V is applied to IC. The following effects are acquired when it was enabled to drive a motor by the high voltage that is not in motor drive IC of the conventional low-voltage system.
Low vs HIGH-Voltage BLDC Motor Control | |||
---|---|---|---|
No. | LOW-Voltage Brushless DC | HIGH-Voltage Brushless DC | HIGH-Voltage Advantages |
1 | Regulate Line down to LOW-Voltage | Not Needed | NO Voltage Regulator losses |
2 | Diode Bridge Rectifier | LOWER Diode Bridge Current | LESS LOSS in Diodes due to LOWER Current |
3 | LOW-Voltage Controller but, HIGHER Current IGBTs | HIGH-Voltage controller with LOWER Current IGBTs | REDUCED IGBT Power Dissipation due to LOWER Current |
4 |
LOW-Voltage Motor
