Piezoelectric motors are increasingly popular for linear motion, but the design of the accompanying drivers is very different from those used by traditional electromagnetic motors.
DC-DC Converters Redefined With 'Micro Modules'
Rudy Ramos  
7/5/2018   Post a comment
DC-DC converters operate at all power levels and complexities. At some low levels it can make sense to design and ‘make it yourself,’ but at higher powers, a pre-assembled module becomes more cost-effective. New ‘micromodules’ shift that point to lower levels.
