Introduction
Cordless power tools are becoming increasingly popular in professional and DIY usage due to their ease of use, portability, and increased safety over mains-powered tools. With the inclusion of brushless DC (BLDC) motors, they are now suitable for most tasks.
However, manufacturers are being chal

The subject of power supplies is potentially very broad and the application of resistors in power supplies is quite diverse. Here we will focus on power supply units (PSUs) designed for use in electronic appliances that nominally require fixed DC outputs ranging from just a few volts up to a few kV.
Whether

For more than thirty-five years, the power MOSFET dominated the power management systems due to its constant technological evolution from its device structure to its applications to circuit topologies. However, at the dawn of the new millennium, power MOSFET reached its theoretical limitations that it became un
