In Figure 2, a long switching interval is observed when a power MOSFET is driven by a microcontroller I/O pin at its maximum rated source current. As seen in Figure 3, transition time reduces significantly with an ADuM4121 isolated gate driver, which provides much higher drive current than...
amongst other systems. Thegateis the electrically isolated control terminal for each device. The other terminals of a MOSFET are source and drain, and for an IGBT they are called collector and emitter. To operate a MOSFET/IGBT, typically a voltage...

Usually this is done with an electronic component called an isolated gate bipolar transistor (IGBT). The amount of energy flowing to the LEDs depends on the duration of the “off” period. The longer the off period the dimmer the LEDs will appear to be....
isolated gate drivers, which sit between the microcontroller (an SPC58) and the power stage using silicon carbide devices, to protect the MCU from power surges and other shocks that could damage the system. The reference design is, therefore, an example of a com...
An effective measure to overcome this problem is to provide an additional connection to the source (Kelvin connection), that is used as a reference potential for the gate driving voltage, thereby eliminating the effect of voltage drops over the source inductance. The achievable efficiency improvement...

The galvanic isolation needs of the solar system vary on the basis of the inverter architecture and the rated power of the system. The DC/AC inverter is comprised of the power transistors like MOSFETs or IGBTs controlled by the isolated gate driver transformers that receive the PWM input from...
I: And now we have an interview with Professor J. T. Lingo, Professor of Linguistics at Chimo University, who is here to talk to us about the growing business of teaching English. Good morning, professor Lingo.P: Good morning.I: I understand that teaching English is becoming “big ...
