Commonly used IGBTs for BLDC motors: Suitable for all kinds of home appliances, preferably single IGBTs

The penetration rate of BLDC motors in both industrial and household applications is continuously increasing. In addition to traditional power tools, vacuum cleaners, and small household appliances, cars, electric two-wheelers, and high-speed hair dryers are also increasing. Therefore, how to choose IGBT single tubes for BLDC motor applications has become an important topic for motor manufacturers.

At present, many domestic motor manufacturers are paying attention to, testing and even mass-producing BLDC motors with FHF20T60A single-tube IGBTs. This is a single-tube IGBT developed and produced by a purely domestic manufacturer: Feihong Semiconductor.

The excellent Vcesat saturation voltage drop and low turn-off loss of the FHF20T60A single tube further improve the efficiency and quality of the BLDC motor. Of course, all this is also due to its advantages such as very short tail current and positive temperature coefficient.

Not only that, the FHF20T60A model also has the characteristics of 20A, 600V current and voltage parameters. The IGBT single tube with this feature is very suitable for use in the motor drive circuit of the BLDC motor.

If an engineer wants to ask what other features it has, here are a few:

1. FHF20T60A single tube has high reliability and reverse parallel fast recovery diode characteristics

2. With 20A, 600V, VCEsat typical value: 1.49V-typ, <1.7V; ID (Tc=100℃): 20A; BVCES: 600V; IF(A) (Tc=25℃): 20A; IF(A) (Tc=100℃): 10A.

FHF20T60A is a field N-channel trench gate stop IGBT that uses Trench Field stop Ⅱ technology and optimized process to achieve extremely low VCEsat saturation voltage drop and make a good trade-off between conduction loss and turn-off loss (Eoff).

At present, the FHF20T60A IGBT single tube has been widely used in various hard switches such as BLDC motor circuits, inverter power supplies, motor drives, air conditioners, AC220V output high-frequency vehicle-mounted sine wave inverters, power factor correction, outdoor energy storage power supplies, etc. It can replace other brands and models: NCE20TD60BF.

The package form of FHF20T60A single tube is TO-220F. In addition to the above fields, it is also recommended that BLDC motor manufacturers in the fan field: fans, exhaust fans, range hoods, hair dryers, HVAC fans, circulation fans, industrial fans, etc. can pay more attention to this pure domestic IGBT single tube.

If BLDC motors want to gain competitive advantages in the markets of fans and pumps, new energy vehicles, and home appliances, it is very important to choose high-quality IGBTs. The FHF20T60A IGBT single tube in the market is a high-quality replacement for the NCE20TD60BF parameter model, which helps improve the stability and reliability of the product.

It is very important to choose the right model for BLDC motor when using 600V, 20A IGBT replacement.
