mosfet driver circuits Sinusoidal? You mean to drive the mosfets 'analog' like in an audio amplifier? Normally the 2 N-ch mosfets are connected to ground with the sources. The centertap is connected to the positive supply. Each mosfet willl pull the transformer winding to ground one by one. Jul 19, 2009 #5 T torpedo2k3 Newbie level 3 Joined

A MOSFET driver IC translates TTL or CMOS logical signals, to a higher voltage and higher current, with the goal of rapidly and completely switching the gate of a MOSFET. An output pin of a microcontroller is usually adequate to drive a small-signal logic level MOSFET. However driving larger MOSFETs is a different story.

Q3 is directly driving the final amplifier MOSFETs (K1058 & J162), which can produce up to 100W RMS power output (theoritically), which can not be applied at the BJT end amplifier (because the BJT is ‘current operated devices’ while the Power MOSFET is ‘voltage operated devices’ which does not require large currents to drive it).

The second stage is the driver stage consisting of transistors Q3 and Q4. The output stage is a complementary push-pull stage based on MOSFETs IRF530 and IRF9530. The output is coupled with the speaker using the inductor L1. The network comprising of R15 and C5 is meant for noise reduction. Capacitors C6 and C7 are power supply filters.
