Winding Technology Comparison

The Hybrid Transformer uses Enertech’s patented Zig-Zag winding technology to mitigate harmonics and minimize power loss.

Conventional Transformer

A structure with forward winding ratio in each phase,
maintaining a 120° phase shift

No harmonic cancellation (X)

Hybrid Transformer

Patented Zig-Zag winding method with forward and reverse windings in each phase, controlling a 30° phase shift

Harmonic cancellation enabled (O)
