Transformer Designer - to calculate design parameters for single pahse transformers. Transformer are widely used in our electrical applications to step down or step up AC voltage. These are used in power supplies, stabilizers, inverters, converters and UPS. This app is complete solution for especially for two winding transformer. This app helps transformer designers to find out different transformer parameters. These parameters are - Transformer Turn/volt - Turns for primary coil - Turns for secondry coil - Amp for primary coil - Amp for secondry coil - Transformer power Disclaimer : We have designed this app at our best.
