How to build the 200 watts home inverter projects

You read the article about 200 watts home inverter projects If you are interested in creating this project.Let’s see how to do.

Starting from to make PCB as shown in Figure 1. and Check for any error of the copper. Especially between pin of IC2-SG3526N. Which is small, easily fail and short circuit Should be extra careful.
Note:
This article is part of 200 watts home power inverter project using SG3526N You can read each section for continuity.

Then put the device in the form in Figure 2. By put lowermost equipment before. Then gradually by higher equipment respectively. To facilitate the operation.

For the 2 ICs in the circuits should put the socket IC. To protect heat from soldering. Which may cause ICs damage. The both power mosfet transistors (Q1 and Q2) Before installed with the heat sink. Must insert by a sheet of mica prior to the body of mosfet short circuit to the heat sink.
And for better cooling efficiency. Should apply silicone cooling pad with mica.

When all the components on the PCB completely. The next step is the wiring to the transformer. And equipment that are outside the PCB. In the example shown in Figure 3, and figure 4 is an example of the power inverter to the finish. Ready to go to trial.

Testing and tuning.

The final stage of the project is The functional testing of the machine. It can work normally or not. Beginning Must provide supply +12 volts from the battery to the circuits. Normal dimmer LED must be on. Then, use the multimeter set range on AC 1000V measure the output voltage.
If the circuit working correctly measured approximately 220 volts. If not for the lack of print – not Short,Enter not guilty. The circuits to work immediately without any customization.

This project should not be used Testing DC voltage 12 volts from the power supply. Because of this power inverters to the power current source is quite high. If using full capacity. Use high current to 10 A. If the power source can not supply this amount. They will enter to the protection status immediately. Because the voltage falls below 12 volts.
Thus, in the experiment or the actual use should be running on battery power. Which can flow over the general power supply.

For ease of implementation. They should find circuits box containing all and connect wire DC input out. The wire used should be no larger than 4 square millimeters.


Under 500 watts is the perfect.

The inverter unit is a compact. Suitable for use with appliances that consume a lot of electricity. Such as fluorescent lamps, LCD TV 22 inch or VCD player generally. Should not be brought to the appliances that consume more energy. Such as irons or electric stove. Because it makes machine stop to the protection status (without damage).

Bringing this project to implement offsite. Such as to camp overnight. May want to use different appliances. Which would have the power source from the battery of the car. The batteries in cars is size from 80 to 100 amps per hour. If the battery is full. Will be able to power machine 200-watt inverter for over 8-10 hours.

The battery is weak. Which, if brought to the inverter fluorescent lamp fluorescent Generally, the size (36 watts) can power your car battery with an inverter and all night long. Without having to ignition. Machine cars leave the noisy and oil. Due to concerns that the wakes in the morning to start the car misfire The battery pack is exhausted.

The voltage 220V 50Hz from this inverter Sine Wave signal is not as light as the perfect home. Frequency 50.00Hz and may not fit. There may be some slight error. Therefore, it should not lead to an electrical device. Or tools that require high accuracy. Such as instrumentation. Which may cause these devices. Working correctly.

Caution, the more important reasons are Be careful not Must use very high input voltage than 12 volts.Because of the high pressure, high output voltage as well. This may result in Equipment & Supplies damage were available. But if the car battery is the power source. I do not have to worry about this problem. Usually because the battery voltage is 12 to 13.5 volts only. Which voltage of this size can not increase the output voltage to cause harm to any of our electrical equipment. Which voltage output power. Will vary according to the input voltage specified in Table 1.
(loaded use the full power 200 W).

Good Day,
I just want to ask that is this inverter is capable to charge the battery automatically?and when the power goes dc will it be automatically supply the power?

Johnson

does inverter increse\multiple\boast power after convertion or does its output depend entirely on the input from the battery i.e the amps and voltage from the battery
