DC/DC converters feature high power industrial drives

The latest DC/DC converters from RECOM, feature needed to power Silicon-Carbide (SiC) MOSFET drivers in efficiency-focused applications like EVs (electric vehicles), renewable-energy conversion, and high-power industrial drives.

The RKZ-xx2005D and RxxP22005D series incorporate superior isolation, providing up to 4 or 5.2kVDC respectively to ensure long-term safety in the presence of high potential differences between control and power circuitry in SiC-MOSFET applications.

By providing asymmetrical +20/-5V outputs, these converters enable the gate driver to apply optimal turn-on and turn-off voltages (VGS). Unlike conventional silicon power transistors, SiC MOSFETs require high VGS for full turn-on, and negative VGS for fast turn-off, to minimise RDS(ON) and switching losses for best overall energy efficiency.

As unregulated 2W converters, the RKZ-xx2005D and RxxP22005D feature power-sharing outputs that can be used with equal-power (asymmetrical current) or equal-current (asymmetrical power) loads.

The RKZ-xx2005D and RxxP22005D series operate at up to 85% efficiency, and are available with input voltages of 5, 12, 15 or 24V. They benefit from a wide operating temperature range from -40 to +100°C (with derating), UL60950 and IEC/EN60950 certification, and RoHS2 and REACH compliance. All units come with RECOM’s three year manufacturer’s warranty for extra peace of mind.
