Magnetics Losses Management.
Magnetics are the most critical components of power electronics design.
A good sizing of magnetics in any power electronics systems is one of the most important things to decrease losses and increase efficiency.
EMC LAB in the R&D department
Watt & Well engineering center got its new in-house electromagnetic compatibility (EMC) lab to test every delivered product. This process ensures the compliance of each product with the EMC certification. This lab dedicated to EMC includes various equipment: LISN 63 A, LISN 16A, spectrum analyzer, various filters and attenuators, common mode current probe among other acquisition. This provides our customers with the best possible follow-up of the on-going project at a short notice.
Mind the GAP - SiC/GaN Driver Boards
Analog Devices teamed up with WATT&WELL to work on a range of high end, SiC MOSFET-based power converters. The collaboration has started with the design of high voltage, high current evaluation boards for ADI isolated gate drivers. Power specifications (1200 V, 100 A), High switching frequencies (> 250 kHz) with a reliable and robust design. The objective of these gate drivers is a showcase to completely evaluate the ADI set of ICs driving SiC and GaN MOSFETs.
Development of a high-performance grid tied battery charger. ADI was thinking into developing a new reference design for the energy industry, they decided to do it alongside of WATT&WELL.
Electric Bike Motor Control
We developed a system control strategy for an electric bike running with a 250 W brushless motor. From brake, pedal sensor, temperature sensors through hall sensor interface, power driver and core control algorithms, we reached the maximum efficiency of energy conversion. Power density increased by 50%.
Harsh environments qualification
WATT & WELL is strong with over 10 years of expertise and experience in harsh environments. Regarding high temperature and vibrating environment, several qualification campaigns are run continuously.
