Designers can meet and even exceed standby-power specifications of the U.S. Energy Star standard and the German Blue Angel Eco Norm thanks to a power MOSFET/pulse-width modulation (PWM) controller ...

Why PWM? Switch-mode converters employ a power semiconductor switch (usually a MOSFET) to drive a magnetic element (transformer or inductor) whose rectified output produces a dc voltage. Efficiencies ...

For IGBTs, the on-state voltage drop is a critical specification to consider. This drop includes both the diode drop across ...

Pulse Width Modulation or PWM technology is used in Inverters to give a steady output voltage of 230 or 110 V AC irrespective of the load. The Inverters based on the PWM technology are more superior ...

Microchip Technology announced a new family of power-conversion controllers and its first-ever family of power MOSFET devices. This new Pulse Width Modulation (PWM) controller and complementary family ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...
