The term "Inverter" is associated with several
different electronic applications.
In logic circuits "inverter" may be a logic
inverter, the equivalent of a "Not" gate.
In analogue signal processing an inverter can be a circuit
which inverts the phase of the signal being transmitted.
In power conversion applications an inverter is an electronic
transformer which converts power from a Direct Current
source into Alternating Current (A.C.)
power. Power conversion inverters can be divided
into two sub-categories, voltage-fed inverters and current-fed
inverters. Voltage-fed inverters are more common than
the current-fed inverters. The electronic
transformers used in inverter circuits
are often called inverter transformers. Inverters produce
A.C. power by switching the polarity of the D.C. power
source across the D.C. power source’s load. The early
inverters used mechanical switches to do the switching.
Vacuum tubes replaced mechanical switches in low power
applications. Eventually semiconductor based switches
(diodes, transistors, F.E.T.s, S.C.R.s, etc.) replaced
both mechanical and vacuum tube switches.
manufactures electronic transformers and Inverter transformers
in a wide variety of shapes and sizes. This includes;
various standard types of “core with bobbin” structures
(E, EP, EFD, PQ, POT, U and others), toroids, and some
custom designs. Our maximum weight and power limitations
are 40 pounds of weight and 2 kilowatts of power. We
have experience with foil windings, litz wire windings,
and perfect layering. For toroids, special winding techniques
such as sector winding, progressive winding, bank winding,
and progressive bank winding can be accomplished to
satisfy your dielectric, creepage distance, capacitance,
