Best Mosfet Inverter circuit

This inveter is great and this inverter is really work too... Visit the original author's page here.

This circuit will provide a very stable "Square Wave" output voltage. Frequency of operation is determined by a pot and is normally set to 60 Hz.

Various "off the shelf" transformers can be used. Or custom wind your own FOR BEST RESULTS. Additional MosFets can be paralleled for higher power.

It is recommended to have a "fuse" in the power line and to always have a "load connected", while power is being applied.

The Fuse should be rated at 32 volts and should be aproximately 10 Amps per 100 watts of output. The power leads must be heavy enough wire to handle this high current draw!

Appropriate Heat Sinks should be used on the RFP50N06 Fets. These Fets are rated at 50 Amps and 60 Volts.
** Other types of Mosfets can be substituted if you wish.

12V DC to 120/230V AC Inverter circuit with IC 555

This is a DC-to-AC inverter circuit diagram which produces an AC output at line frequency and voltage. The 555 is configured as a low-frequency oscillator, tunable over the frequency range of 50 to 60 Hz by Frequency potentiometer R4.

Parts List:
R1_________ 10K
R2_________ 100K
R3_________ 100 ohm
R4_________ 50K potmeter, Linear
C1,C2______ 0.1uF
C3_________ 0.01uF
C4_________ 2700uF
Q1_________ TIP41A, NPN, or equivalent
Q2_________ TIP42A, PNP, or equivalent
L1_________ 1uH
T1_________ Filament transformer, your choice

The 555 feeds its output (amplified by Q1 and Q2) to the input of transformer T1, a reverse-connected filament transformer with the necessary step-up turns ratio. Capacitor C4 and coil L1 filter the input to T1, assuring that it is effectively a sine wave. Adjust the value of T1 to your voltage.

The output (in watts) is up to you by selecting different components.

Input voltage is anywhere from +5V to +15Volt DC, adjust the 2700uF cap's working voltage accordingly.

Replacement types for Q1 are: TIP41B, TIP41C, NTE196, ECG196, etc. Replacement types for Q2 are: TIP42B, TIP42C, NTE197, ECG197, etc. Don't be afraid to use another type of similar specs, it's only a transistor... ;-)

Use proper transformer. If you load electronic device which require 120V AC, then use transformer with 120V in output.
