DC-DC Converters Optimized to Power IGBT & SiC Drivers

GAPTEC Electronic offers the IGBT & SiC dc-dc converter series 5DABT, 5S7BT and 5S7SiC. The converters of the new series are available in SIP7 and DIP24 case designs. All series are equipped with an asymmetrical voltage output and a power sharing mode (asymmetric load possible). The efficiency of these converters is up to 85%. The insulation voltage of the series ranges between 3kVdc and 6kVdc and all units provide continuous short-circuit protection.

The operating temperature range is from -40 to + 105 degrees C. In addition, the units provide very low coupling capacitance. The series complies with UL60950 guidelines. The converters of the new IGBT & SiC series typically find use for the control of IGBT drivers in ac servo drive systems, electric welding machines and uninterruptible power supplies. GAPTEC Electronic guarantees very short lead times. The product warranty is 3 years.

The 4.8W, dual-output 5DABT_D3 Series, and the 5W, dual output 5S7BT_D3 Series, are dc-dc converters for IGBT drivers. Their ultra-low isolation capacitance can improve the capability of anti-interference. The built-in common-ground mode of the unique asymmetric voltage output mode reduces the driver loss of IGBT driver. They feature short-circuit protection and auto-recovery, and can be widely used in: general inverter designs, ac servo drive systems, electric welding machines, and Uninterruptible power supplies.

The 5W, dual-output 5S7SIC_D6 is a dc-dc module power supply designed for SiC drivers, requiring two sets of isolation power supply. The mode of mutual connection after two independent outputs is adopted internally for better energy provision of SiC turn-on and turn-off. Output short circuit protection and self-recovery capabilities are also provided. General application includes: universal converters, ac servo drive systems, electric welding machines, and uninterruptible power supplies.
