Overview of CFW500 AC Drives - cdn.automationdirect.com

IGBTs invert the DC power, simulating a sine wave at the desired frequency (that’s what allows variable speed in AC induction motors). The speed at which the IGBTs are turned ON and OFF is called the Carrier Frequency. In WEG CFW500 drives, the Carrier Frequency can range from 2kHz to 15kHz. Though Carrier Frequency can be adjusted, there are ...

DC-DC Power Converters

MOSFET and diode; however, other semiconductor switches such as IGBTs, BJTs, or thyristors can be substituted if desired. The first converter is the buck converter, which reduces the dc voltage and has conversion ratio M(D) = D. In a similar topology known as the boost converter, the positions of the switch and inductor are interchanged.

MIC5021 - High-Speed, High-Side MOSFET Driver with …

Nov 07, 2016 · IGBTs. The MIC5021 can also operate as a circuit breaker with or without automatic retry. A rising or falling edge on the input results in a current source pulse or sink pulse on the gate output. This out-put current pulse can turn on a 2000 pF MOSFET in approximately 550 ns. The MIC5021 then supplies a
