Transformer losses can be put into three major categories: core hysteresis losses, core eddy current losses, and winding losses. Core hysteresis losses are a function of flux swing and frequency. In all buck-derived applications under steady-state conditions, VIN•D = n•VO. Under fixed frequency operation, volt-seconds and therefore

A variable-frequency transformer (VFT) is used to transmit electricity between two (asynchronous or synchronous) alternating current frequency domains. The VFT is a relatively recent development. Most asynchronous grid inter-ties use high-voltage direct current converters, while synchronous grid inter-ties are connected by lines and "ordinary" transformers, but without the ability to control ...
The lack of high frequency harmonics reduces heating in the transformer due to skin effect and proximity effect within the conductors. Finally the transformer design should be optimised for minimum inter-winding capacitance and good insulation at the expense of increased leakage inductance.
