hi guyz,
i have built a small UPS about 800va (500w). the UPS works perfect. the inverter uses a large transformer to step up AC. i just wanted to know is there a way to make an inverter without this transformer? i mean the transformer is bulgy and heavy and it is wasting about 300watt of my power. how can i get this 300watts back using some technique or combination of MOS or IGBTs? i cant find a circuit which is designed for this purpose but i want to know the technique which may be helpful in making this transformerless.
any help will be appreciated.
Thanks to All.
