Mosfet In Series And Parallel

Even so, on occasion, designers find the need to operate two MOSFETs in a parallel configuration. Generally speaking, as MOSFETs do not suffer from thermal runaway (as can happen with bipolar devices), this makes paralleling them easier. As MOSFETs are voltage-driven, they simply need a stable and uniform voltage. The usual way of connecting MOSFETs in parallel is to just connect the G, S and D of each to the corresponding pin on the others. This will triple your overall gate capacitance so the driving signal should be meaty enough to get them switching hard on and hard off as rapidly as possible. A series circuit shares the same current among components; a parallel circuit shares the same voltage.

Capacitors in series Vs Capacitors in Parallel | Difference between Capacitors in series and Capacitors in Parallel

This page compares Capacitors in series Vs Capacitors in Parallel and mentions difference between Capacitors in series and Capacitors in Parallel.

Capacitors in series

As shown in the figure, if two capacitors are connected in series,following can be derived.
• For two capacitors in series, total capacitance is expressed as follows.
➨1/C = 1/C1 + 1/C2
➨Capacitors in series, total capacitance, C= C1*C2/C1+C2

➨For multiple capacitors in series, total capacitance, (1/C) = (1/C1) + (1/C2) + ... + (1/Cn)

Capacitors in parallel

As shown in the figure, if two capacitors are connected in parallel, following can be derived.
• For two capacitors in parallel, total capacitance is expressed as follows.
➨C= C1+C2
