This invention is designed to eliminate Transformer Core Energy Losses eg. Hysteresis Energy Heat Loss. Hysteresis Losses constitute most of the Transformer Core Losses which decreases the Efficiency and increases significantly to Energy Losses as Frequency increases. Heat Losses can reach the point of igniting the equipment. Cooling methods are costly and difficult to be employed on common smaller Consumer Electronics. Electronics devices are very inefficient when these are operated below their designed Maximum Load Capacity. This invention is designed to increase the efficiency and thus increase the Power Rating of smaller transformers without adding more cooling methods. Most Utility Transformer were installed decades ago. These old Transformers are becoming much more inefficient. New replacements are expensive. The different environmental conditions in a nation makes it impossible to mass produce one or a few models which are very economical and efficient to transfer power, to be cooled and to be routinely cleaned. The Primary Source to this invention can be Direct Pulses or AC Sine Waves. Primary AC Sine Waves are converted by Rectification into DC Pulses to feed the Primary Coil. Transformer Changing DC Pulse Flux Action produces a Pulsed DC Secondary Coil Current and a DC Pulsed Voltage. The Primary Flux Density is doubled in Frequency by the two Primary DC Full Wave Pulses for each original Input AC Sine Wave doubled the Frequency of the Input Primary Coil Voltage and the Output Secondary Voltages, Currents and the circulating DC Flux. The Secondary Coil Output Voltage can be converted into AC Sine Wave Load Voltage by alternating employing one Circuit Network of Triac Pairs for each 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 Voltage. Each circuit employs two Triacs. Each Triac has one Gate Terminal. Each Gate works with its own orientated Polarized Diode to control its own Triac if the Triac has a Voltage across its two Main Terminals, MT1 and MT2. The two Diodes of each circuit when properly biased 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 stops 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 transformer could be a Step-Up. The Load could be a Variable Transformer made up of a Bank of Output Coils and Movable Core, or a Linear / Rotational Voltage Differential Transformer respectively for Linear or Rotational Position Controls. A Worm Gear is used with this Core for the RVDT. Some of the other advantages are the elimination of the Sinusoidal Waves in current Transformer Coils which cause Vibration Wear Noise and Induced Resonance is other structures or circuits. The design uses DC Pulse Waves on both the Primary and the Secondary Coils so that the Hysteresis Losses are eliminated. The loss of Hysteresis Heat Energy Losses no longer affects other components, reduces the 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 costs. Less costly Shielding and design costs are lowered. The Load could be supplied by Filtered DC Currents if the Triac Networks were not 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 Supplies. Through the use of Switches and the use of DC Pulses on both the primary and on the Secondary this invention makes it possible to very quickly transform the Output for other applications. For example the Triac Characteristics make the invention much safer to operate. The Triac has a Saturation Limitation which can protect the Output and a Triac in Parallel 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 drains. A Triac is a bidirectional, three-terminal dual, back-to-back Thyristor (SCR) switch. This 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.
