This article lists various types of audio amplifier circuits using Mosfet. We have tested all these circuits in our lab and we found all of them performing satisfactorily. Mosfet is a 3 terminal semiconductor device used in a wide range of electronic circuits. It works like a JFET but has less current leakage owing to an oxide insulation between the conductors. Mosfet is a good choice for building linear amplifiers owing to its lesser load, and any amplifier made using it is called a Mosfet amplifier. These amplifiers have a wide range of applications, they can be used in many circuits.

Effective date : Year of fee payment : 4. Year of fee payment : 8. Year of fee payment : A soft-switching dc-to-dc converter for providing regulated voltage to a load combines the functions of loss-less soft switching at zero voltage and at a constant switching frequency on the primary side and soft switching at zero current on the secondary side of an isolation transformer for all load currents from full load to no-load and PWM output voltage regulation on the secondary side. The adjustable dead-time is realized by sensing voltages across paired primary side current bidirectional switching element in order to enable alternate turn ON of said pair only at zero voltage, thereby eliminating or greatly reducing switching losses under all load current conditions. The output voltage is regulated by PWM control of the voltage bidirectional switching element comprising one of the following: a bipolar transistor, or a MOSFET in series with a diode, or preferably a saturable reactor in series with a diode to form a magnetic amplifier on the secondary side. With increased demand for faster response and reduced size and weight, switching frequency of dc-dc converters is increasing toward the megahertz range.

High Power 250 Watt MosFet DJ Amplifier Circuit

Project 11 is a descendant of Project 5, which uses standard building blocks of a conventional power amplifier circuit with power MOSFETS output stage. The circuit is as simple as it can get to build an audio power amplifier, but reproduces excellent audio fidelity. Project 11 was the result of revisiting the original circuit and replacing the power MOSFETs and drivers with less expensive and readily available parts while still retaining its sound quality reproduction. Project 11 uses the same schematic diagram as in Project 5 except for the T version. The test procedure for this project is identical with Project 5. In both T and T versions the idle current must be adjusted at 10mA. Readjust the idle current after a warm up period of about 30 minutes.

Uday Patil. IRF is for 70W max according to datasheets. Through Hole, 3 Pin TO Rise time is 30ns and the fall time is 20nS.

Year of fee payment : 4. Effective date : FIELD OF THE INVENTION The invention relates to an ac-to-dc switching converter, and more particularly to a new technique of employing voltage bidirectional switches as the controllable switches, such as magnetic amplifier switches, to provide both unity power factor and independent output voltage regulation in a single conversion stage. Direct bridge rectification of the ac input line into a capacitive filter results in a poor power factor and high harmonic current pollution. This is no longer acceptable due to tightened international regulations governing the power quality and harmonic current pollution of the utility input line from the ac source.

IRF third generation power MOSFETs provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness. The TOAB package is universally preferred for all commercial-industrial applications at power dissipation levels to approximately W.
