1000W Power Inverter circuit diagram:
This is the power inverter circuit based MOSFET RFP50N06. The inverter capable to handle loads up to 1000W, it’s depended on your power inverter transformer. The RFP50N06 Fets are rated at 50 Amps and 60 Volts. Heatsink is required for cooling the MOSFETs. You may add some MOSFETs with parallel connection to get more 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 advantages of this inverter circuit:
This circuit will provide a very stable “Square Wave” Output Voltage.
Frequency of operation is determined by a pot and is normally set to 50 or 60 Hz, Depends on where you live.
SOME “off the shelf” transformers can be used, but with Poor Results. Or you can 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.
The LT1013 offers better drive that the LM358, but its your choice.
The Power transformer must be capable of handling the chosen wattage output. Also, Appropriate Heat Sinks are Necessary on the Mos-Fets.
Using a rebuilt Microwave transformer as shown below, it should handle about 500 watts Maximum. It requires about 18 turn Center-Tapped on the primary. To handle 500 watts would require using a 5 AWG wire. Pretty Heavy Stuff, but so is the current draw at that power.
Simplified Operation is: IC1A & IC1B, Along with IC2A & IC2B and the Transistor form a Voltage controlled Oscillator of which the frequency is adjusted with the 25K ohm pot. IC2C & IC2D are buffers, driving the Mos-Fets, out of phase of each other.
The 13 volt Zeners stabalize supply voltages and limit signals, while the 36 volt Zeners limit spikes from the transformer.

To obtain 1000K, one can use a microwave oven transformer and modified its windings. All depends on the low voltage winding of the transformer.
kindly e mail pdf schematic design of solar pure sine wave transformerless inverter having input 24/48vdc and output 5000 watts at 220vac having battery charging along with parts list. thanks and regards
My transformer is winded for 6 12v batteries, 120aH.
Hi all, You have to use a transformer that is special made for your project, I use a 35kg transformer that is able to give me 5KW of power. You will get poor results from transformers bought from your local dealer, wind it yourself, but it is cheaper to buy an inverter from the local shops. Your battery banks must be able to produce the DC volts needed to generate 5KW, I use 72 - 0 - 72 transformer, total 4 12v batteries 120aH to do the job.
Would this circuit be used for the appliances at home??
welcome to you
Plll sent me the circuit diagram and working of 24 v invertor
i need that all different type invertr t in cricuites
Sir,please give me a part list of 1000watts pure sine wave power inverter.and design of power transformer.thanks..
hi i want wich volt transformer use 1000w invertere
