Abstract :
A coaxially-connected, multielement transformer-rectifier is described for high-frequency power supply applications. Each elemental transformer has an optimally interleaved, single-layer winding, and the coaxial interconnection enables increased output voltage and higher power throughput to be achieved, whilst minimizing the leakage inductance. A leakage inductance of 0.55 μH is achieved in a 2.0 kW, 500 kHz transformer-rectifier.
