Abstract
Multielement transformers offer the prospect of low-profile designs wi th low leakage inductance and good thermal properties. The performance s of both high- and low-voltage transformer designs, employing toroida l cores, are evaluated in ZVS-QR (zero-voltage switching-quasiresonant ) convertors. It is shown that high transformer power density and good efficiency can be achieved.
