The IGBT Protection

. Principio di funzionamento I primi IGBT erano tiristori modificati per potersi accendere con un comando in tensione. Consider the BJT equivalent circuit of a thyristor and a MOSFET transistor is added between the collector and emitter ...

Fast MOSFET Test

. Often in online discussion I find myself having to explain how a mosfet is head, the test with a multimeter is the fastest but, not from the certainty that the component functions properly in impulsive regime. Rummaging through the drawers ...

Fuel Cells

. Rechargeable batteries are not clearly enough to power electric cars for a considerable period of time. Without reliable and capacious batteries, you lose the challenge of mass mobility. So the industry is working ...

Albert Einstein and the GPS
