Thermal management for next-generation EV charging
While electric vehicles have existed as long as gas vehicles, they have only become mainstream over the last few years. With significant improvements in…
All you need to know about potentiometers
Potentiometers, or ‘Pots’ as they are commonly known among engineers, are essentially resistors that incorporate a mechanical adjustment mechanism enabling their resistance to be…
Power MOSFET and it’s characteristics
This post tells about power MOSFET characteristics and operating modes. Power MOSFET is a unipolar three-terminal semiconductor device that controls the large amounts of…
Complex conductance. Active and reactive power
Complex conductance Y is the value, reverse to the complex resistance Z, where Y=1Z=ye-jφ. Complex conductance is measured with Siemens (1Ohm), Y=1R+jX=R-jXR2+X2=RR2+X2-j XR2+X2. Ohm Law’s using the conductivity…
Voltage / power
To move an electrical charge in a specific direction you need to apply some force. This force is called by an external electromotive force…
