What should be considered for DC/DC Converter in IGBT Applications
- Output voltages: +15V /-5V to -10V
- Coupling capacitance: < 15pF.
- Temperature rating , converter isolation, gate power requirement, efficiency …
- The same considerations apply in principal to gate dives for SiC and MOSFETs.
- 2.8W QAxx1 series, 4.8W QAW series and QA01C are DC/DC converters specialized for IGBT/SiC MOSFET driver.
DC/DC Converter for IGBT/SiC MOSFET Driver
QAxx1 series are DC/DC converter specialized for IGBT driver. This series integrate driving IC’s features and provide +15/-8.0VDC asymmetrical output voltage which maximize reduce driving consumption. With output current up to 120mA, it meet a wider power requirement of IGBT.
This series also features high efficiency up to 81%, operating temperature of -40℃ to +105℃, ultra-low isolation capacitance (6PF), max. capacitive load (1000uF) and 3000VAC isolation. 12VDC, 15VDC and 24VDC input voltages are available now.
