Meter measurement circuit (three-phase)

Analog Devices, Inc. (ADI) announced the Power by LinearTM LTC7840, a two-phase asynchronous boost controller that drives two external N-channel power MOSFETs.

TDK Corporation introduced a new line of EPCOS MKP (metallized polypropylene) Y2 film capacitors for EMI suppression - B3203* series capacitors. Compared to conventional models rated at 300 V AC, the new capacitors are rated for operation up to 350 V AC and have capacitance values ​​ranging from 4.7 nF to 1.2 μF to ensure stable capacitance values ​​under severe environmental conditions.
