DC/DC converters for SiC and IGBT applications

Richardson RFPD has announced the availability and full design support capabilities of a new series of DC/DC converters rom RECOM Power (RECOM).

The RxxPxxyyD Series devices feature 6400 VDC isolation and <10 pF isolation capacitance and have been designed to fulfill the demanding requirements of high slew-rate SiC transistor drivers.

These new DC/DC converters can be used with equal power (1W + 1W) or equal current (1.6W + 0.4W) driver applications, as the dual outputs feature automatic power sharing. The internal transformer uses a pot-core to physically separate the input and output windings, however the devices still fit in industry-standard SIP7 cases. Input voltage options of 5, 12, 15 or 24 V are available, and the RxxP2xxyyD Series is safety-certified to the latest UL/IEC62368 standard (certification pending).

Additional key features of the converters include +20/-5 V and +15/-3 V asymmetric outputs for SiC driver applications, +15/-9 V asymmetric outputs for IGBT driver applications, and optional continuous short circuit protection.

The benefits of replacing plain old paper with e-paper displays in automotive assembly plants
Efficiency is at the heart of automation, and that is nowhere more apparent than in the manufacture of automobiles. The Ford Motor Company is widely credited with inventing the moving assembly line, but the concept of moving the assembly, rather than the worker, dates back centuries.
