Bi-Toroid Transformer Tests
The Bi-Toroid Transformer is designed to convert Reactive Power to Real Power.
This is accomplished by introducing an additional secondary coil and alternate
flux path route – keeping the primary coil isolated from the secondary induced
BEMF magnetic fluxes
The extra energy required to produce a transformer that operates at over 100% efficiency
comes from the fact that the two secondary coils self regulate their own flux required to
maintain the voltage across the load and the primary coil is unaffected by secondary load.

Table 1 Conventional Transformer vs Bi-Toroid Transformer Efficiency Comparison
The table above shows the efficiency variations for the Bi-Toroid Transformer during the
period of July 10th to July 18th, 2009.
TEST #1 employs a “split” primary core – where an “artificial” air gap is inserted to
increase core reluctance.
TEST #2 employs a solid core – where the core is just sitting on the secondary core – also
facilitating an air gap and higher reluctance between the primary core and secondary
core.
TEST #3 employs a solid core (slightly thicker than test #2) which is physically clamped
to the secondary core – thus removing as much air gap as possible. A new primary coil is
included in the test which has the same wire gauge and coil resistance as test #2.
TEST #4 is a Conventional Transformer.
TEST #5 employs a 10 ohm load in place of the 27 ohm load.
TEST #6 is includes additional windings on Secondary #1.
