STMicroelectronics' 1200V IGBT Series of power transmitters was created to reduce the environmental impact of daily-use equipment such as home appliances, HVAC systems and industrial machines. The transmitter was designed to minimize two major sources of energy loss — conducting and switching.
According to STMicro, the transmitter's lower switching losses were engineered to allow a higher operating frequency, which in turn permits smaller and lower-cost components to power-control circuits. Its compact, industry-standard TO-247 package is intended to save component count by integrating the ultra-fast freewheeling diode required by most circuits.
The IGBT was also designed to survive short circuits lasting up to 10 µsec, making them resistant to common causes of motor-controller failures such as an error in the gate drive signal, shorting at grounding and breakdown of motor phases-to-phase insulation. The goal is to improve motor reliability and save on repair and replacement costs.
