Quick Learning: Benefits of low Qrr MOSFETs in motor control applications

It is common practice in motor control applications to use a resistor in series with the MOSFET’s gate to reduce the switching speed (dv/dt) and the resulting high frequencies that cause EMI emissions. In this video, Nexperia’s Stein Nesbakk explains how the gate resistor contributes to MOSFET heating due to extended operation in linear-mode. Watch Stein explain how ‘NextPower 100V’ low Qrr mosfets are helping to reduce the current surge (Irr) & subsequent voltage spike & ringing which also delivers up to 10dB improvement in radiated EMI.
