This invention is designed to eliminate Transformer Core Energy Losses eg.
Energy Heat Loss. Hysteresis Losses constitute most of the Transformer Core
decreases the Efficiency and increases significantly to Energy Losses as
Heat Losses can reach the point of igniting the equipment. Cooling methods are
difficult to be employed on common smaller Consumer Electronics. Electronics
very inefficient when these are operated below their designed Maximum Load
This invention is designed to increase the efficiency and thus increase the
Power Rating of
smaller transformers without adding more cooling methods. Most Utility
installed decades ago. These old Transformers are becoming much more
replacements are expensive. The different environmental conditions in a nation
impossible to mass produce one or a few models which are very economical and
transfer power, to be cooled and to be routinely cleaned.
The Primary Source to this invention can be Direct Pulses or AC Sine Waves.
Sine Waves are converted by Rectification into DC Pulses to feed the Primary
Transformer Changing DC Pulse Flux Action produces a Pulsed DC Secondary Coil
and a DC Pulsed Voltage. The Primary Flux Density is doubled in Frequency by
Primary DC Full Wave Pulses for each original Input AC Sine Wave doubled the
of the Input Primary Coil Voltage and the Output Secondary Voltages, Currents
circulating DC Flux. The Secondary Coil Output Voltage can be converted into
Wave Load Voltage by alternating employing one Circuit Network of Triac Pairs
Single DC Output Pulse to a Common Load. Alternating DC Pulses are fed by two
independent circuits such that the Common Load has an alternating Sine Wave
Each circuit employs two Triacs. Each Triac has one Gate Terminal. Each Gate
its own orientated Polarized Diode to control its own Triac if the Triac has a
its two Main Terminals, MT1 and MT2. The two Diodes of each circuit when
by the Original Initial Primary AC Sine Wave will alternatively . Alternating
half 180 degree
waves pass the Zero Axis of the Initial Primary AC Sine Wave to signal their
own Triac to
conduct when the Triac has a Voltage across its two Main Terninals. The Triac
conducting when its Main Terminals have a Voltage of Zero Volts. There is a
slight delay by
the DC Power Pulses on the Main Terminals so the Triac Pairs go Off The
be a Step-Up. The Load could be a Variable Transformer made up of a Bank of
and Movable Core, or a Linear / Rotational Voltage Differential Transformer
Linear or Rotational Position Controls. A Worm Gear is used with this Core for
Some of the other advantages are the elimination of the Sinusoidal Waves in
Transformer Coils which cause Vibration Wear Noise and Induced Resonance is
structures or circuits. The design uses DC Pulse Waves on both the Primary and
Secondary Coils so that the Hysteresis Losses are eliminated.
The loss of Hysteresis Heat Energy Losses no longer affects other components,
drain on the batteries and the utility supplies even at no-load conditions,
lowers the cost of
employing new safer expensive environmental cooling materials and the running
costly Shielding and design costs are lowered.
The Load could be supplied by Filtered DC Currents if the Triac Networks were
connected between the Secondary Coil and the Load. This way the Transformer
can act as a
DC Current or as a DC Voltage Signal Amplifier. Applications are DC Welding or
Through the use of Switches and the use of DC Pulses on both the primary and
Secondary this invention makes it possible to very quickly transform the
Output for other
applications. For example the Triac Characteristics make the invention much
The Triac has a Saturation Limitation which can protect the Output and a Triac
with a Load can with a Series Breaker or fuse protect against Overvoltage on
the Load. These
two safety features of this invention are helpful for running motors and
welders safely. Thus
by using Triacs in the design to reduce Hysteresis Energy Losses other
economic and safety
advantages are obtained. Industry must save on the constant NO-Load energy
A Triac is a bidirectional, three-terminal dual, back-to-back Thyristor (SCR)
device can switch the current in either direction by applying a small current
of either polarity
between the gate and one of the two main terminals.
Since it can run cooler, it has significantly improved % Voltage Regulation.
The Embodiments of the Invention in Which an Exclusive Property or Privilege
Claimed Are Defined As Follows:
1. This Invention uses Rectified AC Sine Waves converted to DC Full Wave
both the Primary and on the Secondary Winding Coils of a Transformer, Fig 6.
2. This invention is not the typical Pulse Transformer which uses switching of
Pure DC to
create Square Waves but instead it employs Full Wave AC Sine Waves which are
Rectified to Full Waves to produce DC Pulses or Full AC Sine Waves for
Electronics or Utility Transformers for higher efficiencies, Fig 17A, 17B..
3. Note that this invention was designed to produce only Positive DC Pulses or
Alternating Output Sine Waves to increase the efficiency of the Transformer
increase the availability of the number of DC Pulse and AC Sine Wave
4. These DC Rectified Full Wave Pulses eliminate the Hysteresis Loop Energy
Losses and its contribution to direct and indirect Component Energy Heat
2., 5., 8.
5. DC Pulses do not increase heating losses as the Frequency increases because
Alternating Sine Waves contribute to heating by Hysteresis Loop, Fig 2., 14.,
6. This design helps all Transformers which are small or large to operate
maximum efficiency because they never always run continuously at Maximum
Efficiency Load Capacity and these often run continuously at No-Load, Fig2.,
7. This Transformer Invention is designed to operate much cooler because of
the of the
elimination of the Hysteresis Energy Heat Losses, Fig 2.
8. Lower Transformer Heating reduce the amounts of cooling material and their
running costs Fig 2., 7.
9. Lower Heating Losses increase the Transformer's Safety Rating.
10. Lower Heating Losses allow the use of smaller size efficient transformers
frequencies, higher power and higher voltages., Fig 14
11. Cooler Utility Transformer Designs can be made much cheaper because less
environmentally friendly cooling chemicals are required Fig 7.
12. Conducting wires which are cooler reduce the Copper Wire Sizes and their
and the Copper Energy Losses, Fig 5., 8.
13. DC Pulses do not contribute to Resonance Losses in adjacent metals Fig 5.,
14. DC Pulses do not contribute to annoying Vibrations and Noise Losses in
metals and bases.
15. DC Pulses do not require as much costly material Shielding and its energy
Losses, Fig 5., 7., 9.
16. The employment of the Triacs Current Saturation and Overvoltage
can protect the Load from High Short Circuits Currents and High Output
Fig 1A,. 1B.,, 7A., 17B., 17C.
17. The basic invention design can be operated very easily, quickly and safely
for other purposes such as DC Welding or a Filtered Power Supply.
18. The Output Secondary DC Voltage Pulses can be easily converted back to a
Wave-Form for applications as a Variable Transformer or as a Linear or a
Differential Transformer, Fig 10., 11.
19. Cooler Designed Transformer do not require as much expensive insulation so
more economic and can be more compact, eg Laptops Fig 5., 7., 9.
20. This invention produces better Lower % Voltage Regulation by having less
Losses and higher Induced Output Voltages by this method of " cooling" ie. No
Hysteresis Heating Fig 5.
21. This invention uses DC Pulses on both Coils which eliminates the effects
Heating Losses so a Resonant Transformer as a Load can be a practical
Output Device which can supply high Output Current and high Output Voltages
through the employment of a Series Capacitor in Resonant with an Inductive
Load eg. Inductive Heating, Fig 20..
22. Consumer Electronics, Home Wiring Systems, Mobile or Isolated Safety/
Devices, Transportation Units and Agricultural Systems can be more reliable,
economical and portable, Fig 7.
23. Alternative Energy Devices can now become more widely produced and power
independent piratical and profitable enterprises, eg Water Irrigation and Row
Vegetable Hydroponic or Fish Growing Systems.
24. Electronic Switching eg Square Generator operates more quickly than using
Relays for more accuracy and safety with respect to Output Voltage Circuits,
