500W Mos-Fet Power Inverter from 12V to 110V/220V
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 approximately 10 Amps per 100 watts of output. The Power leads must
be heavy enough wire to handle this High Current Draw!

This DC to AC inverter circuit work based on
unstable multi vibrator does. In this circuit, IC CD4047 is chosen as a
heart of unstable multivibrator, because this IC type gives a
complementary output that has opposite phase to another ( pin 10 and 11
as seen in Figure 1), and has 50 % duty cycle that satisfy to generate a
pulse for inverter.

DC13.8V to DC250V Inverter Circuit Diagram
I have done a lot of work with valves in
recent years. For me valves have many advantages, least of all the
price; since they are now "obsolete" it is quite easy to get hold of
them for next to nothing at rally's and junk sales. I recently purchased
a couple of hundred battery valves for less than SEK1 (US$ 0.15) each.
The biggest problem with valves is the PSU needed to provide +250 vDC
and 6.3 vAC for the filaments. The transformers are no-longer available
at a reasonable price, but a pair of 12v-6v-0v-6v-12v mains transformers
will do the job just as well. For portable use only one transformer is
required together with a pair of power transistors such as 2N3055 etc.

12V to +-20V Automotive Power Converter

12V to +-20V Automotive Power Converter Diagram
The limitation of car supply voltage (12V)
forces to convert the voltages to higher in order to power audio
amplifiers.
In fact the max audio power x speaker (with 4 ohm impedance) using 12V
is (Vsupply+ - Vsupply-)^2/(8*impedance) 12^2/32 = 4.5Watts per channel,
that is laughable...
For powering correctly an amplifier the best is to use a symmetric
supply with a high voltage differential. for example +20 - -20 = 40Volts
in fact 40^2/32 = 50 Watts per channel that is respectable.
This supply is intended for two channels with 50W max each (of course it
depends on the amplifier used). Though it can be easily scaled up or
the voltages changed to obtain different values.

24V to 12V 400W DC Inverter Circuit Diagram
24V to 12V 20A 400W DC to DC Inverter. Does little to change my PV system 12v 24v me the problem arose of what to do with investors who already had 12V. I was looking for a pattern online and found several schemes with linear regulators 20A, this solution although quite simple, due to the huge losses they have is not advisable. Ideally, a converter switched, high-performance. At the end I found nothing I liked and decided to design my own. Circuit characteristics: Output current: 20A at 12V (15A continuous and 30A Momentary), Input voltage: 18 to 30V DC, Output voltage: 5 to 20V, Operating Frequency: 70kHz, Effectiveness: 95%, 400W maximum power, Protections: Above current (30A) in the F1 circuit, D1 and F1 polarity in the circuit.

Small 1.5V to 5V or 12V DC/DC converter with
LT1073 chip. The IC is available in three different versions, depending
on output voltage. Two with fixed output voltage of 5V and 12V, and the
most interesting that can be adjusted. The adjustment is done through a
voltage divider with two resistors, of mass, output and Terminal 8,
internally connected to the voltage comparator IC, which is responsible
for stabilizing the output voltage.

This is a 500W DC-to-AC inverter circuit
diagram which produces an AC output at line frequency and voltage. 12VDC
to 220V 50Hz inverter circuit will power 220V or 110V appliances from
12V car battery. The circuit is easy to make and is low cost. Use proper
transformer. The output (in watts) is up to you by selecting different
power rating transformer and power transistor rating. If you load
electronic device which require 120V AC, then use transformer with 120V
in output.
