With continuing worldwide popularity, smart devices such as phones, pads, watches and glassed has become more sophisticated. Increasing strong demand for smaller insulated transformers, an ultra-small transformer has been developed by adopting an insulated hybrid structure with the size of W16.5 x L19.5 x H10.5 mm 3, whose volume is 65% smaller than conventional insulated transformers. The author's new transformer has been improved in terms of noise reduction by 5-15 dB, power efficiency increase by 2%, and production efficiency by 50%. Relevant analyses are to be given.
