A mild hybrid integrated starter generator (ISG) must repeatedly switch high currents at 48 V to start the engine, recuperate braking energy, and provide torque assist, all while fitting within the tight space underhood as well as thermal budgets.
Vishay's power MOSFETs drive high efficiency three-phase ISG motor stages with PWM switching frequencies as high as 20 kHz, while our DC-Link film capacitors and low inductance current sensing resistors handle the rapid, high current switching the ISG inverter demands.
Behind 48 V mild hybrid ISG efficiency is The DNA of tech.®
