Control Technique Cuts Flyback Input Capacitance

Microprocessor-based devices require a regulated power-supply unit (PSU) that detects the loss of input power and continues to supply power for the length of time it takes to complete the process of ...

MOSFET Synchronous Rectifiers Require Attention to Gate Charge

The switching speed of a power MOSFET charge-controlled device depends on the speed with which an associated gate driver circuit can charge its input capacitance. For the last 20 years, many excellent ...

MOSFET parasitic capacitance change in non-zero current and voltage bias conditions

Abstract: Power MOSFETs have been primarily designed for switching applications, in which case they are operated to the best extent possible either at zero drain to source voltage or at zero drain ...

Characterizing the dynamic output capacitance of a MOSFET

According to precedence, MOSFET datasheets show output capacitance at a single measured voltage. While these values were good enough for relative comparison between products in the past, it is ...

C-V measurement challenges in validating power-semi designs

High-voltage capacitance-voltage (HV C-V) measurements are an increasingly important for characterizing the latest generation of wide-bandgap power semiconductor devices because the measurements are ...
