600 Watt Quasi Amplifier With Mosfet IRFP460
ACTK 400/600 Watt
Two versions of a robust module capable of delivering high powwer for extended periods. The Actrk400 uses 6 n-channel Mosfets in the output stage to deliver around 400 watts into 4 ohms while the Actrk600 uses 12 n-channel Mosfets in the output stage to deliver power in excess of 600 watts into 4 ohms. One constructor has achieved almost 900 watts with the Actrk600 layout using 12 IRFP460 Mosfets.

Mosfet Battery Charger
Battery Charger series with the MOSFETs are designed to charge batteries from an AC current source charging current with a maximum capacity of 1A, and can be modified in order to provide a higher flow by replacing the value of Q1, R1, D1-D5, and T1 with a greater ability high on "battery charger circuit with mosfet" this. The series charger is working at the point of maximum load line of the ability of Q1, so that Q1 needs to get serious attention to cool it and make re-assembly croscek this battery charger before use.
NiCad batteries have the capacity specifications in units of mAh (Mili Ampere Hour), which is defined as "C". The value of this interpretation of capacity C that can be saved by tesebut NiCad battery. To charge the NiCad battery in a normal (not Fast Charge) used in the formulation of charging current 0.1 C NiCad batteries are in charge for 12 hours. Suppose the battery capacity is 4000mAH then filling current 400mA for 12 hours. The advantage of charging the battery by 0.1 C this formula is to create long-lasting battery is not easily damaged or otherwise not charge the battery too quickly run out.
Output current from the battery charger circuit with mosfet is controlled by the sum of the zener reference diode and the base-emitter connection of PNP transistors. PNP transistor provides negative feedback to the gate MOSFETs. As seen in the scheme. Flow output is determined by the value of R1 is determined by:
Power dissipation of R1 will be the same:
PR1 = 3.2Volts Iout *
R1 resource capacity and heatsink Q1 adjusted charging current.

200W MOSFET Power Amplifier
Here is a circuit that uses a mosfet amplifier as the main booster, or the basis of this booster Amplifier. Circuit which uses MOSFET Power Amplifier is powered by the output more than 200W Speaker 8 Ohm impedance. We also include a suitable power supply circuit with the use of MOSFET amplifier with 200W of power, not only of his course Schematic diagram for the layout design is also already there.

High HiFi Power Amplifier with MOSFET
Circuit amplifier "High Power HiFi Power Amplifier With MOSFET" is capable of giving the output power to the load speakers 240Watt and 380Watt 8Ohm to load 4Ohm speakers.
Voltage source to a series of power amplifiers "High Power HiFi Power Amplifier With MOSFET" This is a CT 25V 50V 25V to 50V CT of transformer CT. In making this power amplifier needs to be installed heatsinks on the power amplifier (MOSFET) in order to avoid excessive heat. The series of power supply to power amplifer can use the transformer 5A-20A and 35A mounted diode bridge and capacitors for a minimum of 2x 10.000uF electrolit. Details for the power amplifier circuit can be seen in the following figure.
High Power Series HiFi Power Amplifier With MOSFET can modify to increase power output by doubling the final power amplifier is based on the diiginkan. Power generated from doubling the final power amplifier will also double its power output of power amplifier circuit "High Power HiFi Power Amplifier With MOSFET" it.

Mosfet Power Amplifier 100 Watt
At this time a unsophisticated MOSFET amplifier or else power Amp which Output power is plus/minus 100 Watt/RMS with 8 Ohms otherwise ohter plus/minus 160 Watts /RMS with 4 ohms.

Regarding this circuit simplicity, The distortion is plus/minus 0.1 %. In support of mob-width -3 db(decibel) is increase for 4 Hz to 96 Khz, it is narrow by C1, R1, C2 and R2. Taking part in the two transistors are T1 and T2 makes a initial differential stage part, So,current source(I) of +/- solitary mA is put with resistor R3. In favor of the upgraded project, The current source(I) is new efficient in stability. Coil P1 allows a fine tuning of dictate current voltage on amplifier’s output. Place the Coil P1 with it’s partially usefulness in favor of first power up, so therefore break it unhurriedly for a lowest DC output voltage. custom a essential quality compoment.
