The Principles of the Tran-energy machines US patent US35,654 (WO 2009/112877) and PCT number PCT/IB200800796, which is incorporated herein by reference, describes the principles in the recovery of electric energy derived from the energizing of primary winding after producing the desired work, and harvesting the electric energy from secondary winding caused by increasing and decreasing in magnetic flux of primary winding during energizing and de-energizing.
EPO application 14075049.8-1809, which is incorporated herein, describe a method and circuit for capturing electric energy utilized in energizing coils with capacitors and utilizing the capacitors as part of a voltage source to energize the coils.
The method that utilizes a time-varying current to build up a changing magnetic field in primary coil of a transformer. The changing magnetic field can:
1—interact with another magnetic field to perform desired work(s);
2—induce an inductive voltage across the secondary coil of winding on the main magnetic path;
3—deflect the magnetic flux of permanent magnet in the main magnetic path, consequently magnetic flux of permanent magnets springs over air gaps to a subordinate (sub) magnetic path (less reluctance), therefore sub-inductive voltages appear across the sub-secondary windings, wrapped around the main-, sub-magnetic paths.
High-potential electric charge from voltage-source, after releasing potential energy through a primary coil of winding, can be stored on capacitor, after that, the capacitor is in series with the voltage source, to supply electric charge with high-potential energy to the primary coil of winding. The same method of recovering the utilized electric charge can be applied for all instruments of the device.
In R-L or R-C or R-L-C electric circuits, at DC voltage-source, when switching ON respectively OFF, the current does not reach its desired amperes immediately, respectively zero ampere, but needs a short duration of time to change its values.
Changing current causes changing magnetic flux. This is the basic for DC pulse transformer, moreover, with no voltage-drop full-wave bridge rectifier circuits at primary, secondary and sub-secondary coils of windings, electric energy can be regained, when magnetic flux in primary coil of winding decreases. Simultaneously more electric energy can be harvested at secondary coil of winding, and at sub-secondary coils of winding, wrapped around sub-magnetic paths.
When charging or discharging a voltage-source that consists of capacitors in series or capacitor and battery in series, the same quantity of electric charge will flow through the voltage-source.
High-potential electric charge can be formed and stored in low-leakage, low capacitance and high-voltage capacitor, not only by mean of a suitable capacitance, but also by Voltage-Doubler circuits, if needed. The theoretic operations of Voltage-Doubler and the well-known full-wave bridge rectifier circuit are not described here.
High potential electric changes, stored on appropriate capacitors of primary, secondary, and sub-secondary coils of winding, can be used to recharge the selected voltage source by three ways:                1—Directly connected with the positive pole of the voltage source or via an electronic switch to control the following order of recharging;        2—Through a primary winding of a transformer, via an electronic switch, low-side of the transformer is connected with the positive pole of the voltage source. By this way, during the short time of transferring, the high-potential electric charge from capacitor can recharge the voltage source at the same time with inducing an inductive voltage across the secondary winding. Electric energy from the inductive voltage can be stored in appropriate capacitor for the next transferring.        3—The capacitor with high-potential electric charge is in series with an another voltage source that voltage of the one voltage source is equal with the selected voltage source. The in-series voltage source is connected with a primary winding of a transformer-containing permanent magnets via an electronic switch at high-side, low-side of the primary winding of the transformer is via an electronic switch, connected with the positive pole of the selected voltage source. When high-side and low-side switches are ON in a predetermined time, a desired time-varying current flows through the primary winding to recharge the voltage source, at the same time, it induces inductive voltages across all windings, related with the changing magnetic field of the primary winding. When high-side and low-side switches are OFF, electric energy in all windings flows to the appropriate capacitors, stored there and ready for the next transferring. The no voltage-drop full-wave bridge rectifier circuits or the voltage-doubler circuits are not described here.        
With two electronic switches, preferably without intrinsic body diode, at high-side and low-side, in OFF position, the primary coil of winding becomes an isolated voltage source, when regaining electric energy from collapsed magnetic field or the coming and going of magnetic field from permanent magnets, related with the primary winding.
Directions of magnetic flux of permanent magnets can be deflected by interaction with changing magnetic flux of primary winding. Owing to this, more inductive voltages appear across the coils of winding, wrapped around the main magnetic core, the sub-magnetic cores. Therefore, more electric energy can be harvested.
Soft magnetic materials with high magnetic permeability, low coercive force, can be used as magnetic wires. A multi-strand magnetic wire, combined of soft magnetic wire and for example, copper magnetic wires, or specially, magnetic wires, made of soft-magnetic material clad copper wire can be used to reduce the electric resistance and increase the strength of magnetic fields. Further drawing and description about these coils of winding, shall be done in the next application for patent of the Tran motors\generators.
For electronic switches, controllable switching ON\OFF in following order is essential to make very high-efficiency Tran-generators.
