Embodiment Construction
[0432] The main difference between a new type of transformer and a traditional transformer is the addition of an auxiliary secondary winding, which forms a loop with a capacitor. Because the primary and secondary windings exist in traditional transformers, and their functions in a new type of transformer are similar to those of traditional transformers.
[0433] A new type of transformer has many differences between the ideal state and the actual state. Most of the differences already exist in the ideal state and actual state of the traditional transformer, such as: magnetic flux leakage of the iron core, voltage loss and Joule heating loss of the winding, hysteresis loss and eddy current loss in the iron core, etc., and these differences will not be discussed in this paper. illustrate.
[0434] In the ideal state of a new type of transformer, it is assumed that the excitation current i in the primary winding 0 The phase of (t) lags behind the terminal voltage u 1 Phase of ...

The invention relates to a novel transformer. On the basis of the traditional transformer, an auxiliary secondary winding is additionally arranged, and the winding and a capacitor form a loop; the impedance of the capacitor is greater than the inductive reactance of the winding, and the phase of current advances the phase of total voltage; when current passes through a primary winding, the induced electromotive forces on a secondary winding and the auxiliary secondary winding are e<2>(t) and e<3>(t) and have same phases; when the secondary winding and a load form a loop, the phase of the current lags behind the phase of the e<2>(t) by Pi / 2 and the generated magnetic induction intensity of the current is Bn<2>(t); when the auxiliary secondary winding and the capacitor form a loop, the phase of the current lags behind the phase of the e<3>(t) by Pi / 2 and the generated magnetic induction intensity of the current is Bn<3>(t), and the phase difference is Pi; when the Bn<2>(t) and Bn<3>(t) are equal, the inductance to an arbitrary winding is zero; and when power in the secondary winding is output, input power in the secondary winding is not increased so as to make output electric energy greater than input electric energy. The device can be used for providing electric energy.
Description
【Technical field】 [0001] A novel transformer is an improvement to the existing power transformer, and the technical field belongs to electrical engineering. 【Background technique】 [0002] Usually, alternating current is passed through the transformer. Although there are many waveforms of alternating current, this article takes the alternating current of simple harmonic waveform as an example to illustrate. Unlike direct current, the electromotive force, voltage, and current of alternating current are functions of time. Like mechanical simple harmonic vibration, the alternating electromotive force e(t), alternating current voltage u(t) and alternating current i(t) of alternating current can be expressed by the sine function or cosine function of time t. Taking the cosine function as an example, the alternating current Electromotive force e(t), voltage u(t) and current i(t) can be expressed as: [0003] [0004] [0005] [0006] in: [0007] e 0 is the peak valu...
