Viper31 is a mains voltage converter for ac-dc power supplies from STMicroelectronics which allows PSUs to be constructed that consume only 20mW no-load at 230Vac, while delivering up to 18W when configured as a universal (85 – 265Vac) fly-back converter. Also, consumption is <430mW at 230Vac with a 250mW load. It can be used in isolated ...

UnitedSiC has revealed four 750V silicon carbide power transistors, the first devices from its fourth generation process it unveiled earlier this year. The unusual 750V rating is to allow additional design margin for 400V or 500V battery and bus applications compared with 650V devices, and improvements compared with the company’s third generation means that “gen4 750V ...
