Formula E racers to get lighter thanks to SiC inverters
Full SiC power modules will form the basis of the inverter on the Venturi Formula E team in the FIA Formula E 2017–2018 (season four). The racing season will start on December 2nd and 3rd in Hong Kong. The SiC power modules were devised by ROHM. The inverter for season four features embedded full SiC […]
Ultra-compact 3-W wall-plug adapters meet DoE Level VI, CoC Tier 2 efficiency standards
A new series of 3-W wall plug power adapters are dubbed the SWI3‑N and SWI3‑N‑USB series, available with North American input blades, and the SWI3‑E and SWI3‑E‑USB series, featuring European input blades. They are all certified to meet the current average efficiency and no-load power requirements enforced by the US Dept. of Energy (DoE) Level […]
High-density 15/20-W ac/dc medical-grade power supplies
Two compact and miniature on-board type medical grade ac/dc power supplies are the encapsulated-type MPM-15/20 and PCB-type MFM-15/20. The new MPM and MFM series are only one-third the size of previous generations, but have a wider operating temperature, higher efficiency and lower no load power consumption. The designs of these two series comply with IEC/EN60601-1 […]

Isolated dc-dc converters feature ±1% regulation
Vicor Corporation announced the expansion of its family of isolated, regulated DC-DC converter modules (DCMs) in ChiP packages, with a range of ±1% voltage regulation devices. With power densities of up to 1,032 W/in3, the new series will offer engineers the option of directly driving loads that require tightly regulated output voltages. Vicor’s current family […]
Ultra-high-voltage 1.75-kW bus converter hits 97% peak efficiency, power density of 700 W/in³
Vicor today introduced a new fixed-ratio, ultra-high-voltage bus converter (UHV BCM) to its bus converter module (BCM) portfolio. The new 700V K of 1/16 BCM offers a power level of 1.75 kW and a peak efficiency of 97%, with a power density of 700W/in³. The device is available in the thermally adept 4414 (111mm x […]
DC-DC converters deliver up to 6A and 12A in top- or bottom-side mount
Bel Power Solutions announces the new SLDM Tunable Loop SLDM-06D1Ax and SLDM-12D1Ax modules, which are ultra-low profile, non-isolated DC-DC converters that deliver up to 6A and 12A with maximum flexibility of being mounted on the top side or bottom side of the host PCB. The SLDM modules fit into the smallest, tightest spaces (only 2.8mm high, […]
