Embodiment Construction

[0366] In the transformer whose output is a resonant circuit, the resonant circuit is the key to realize that the output electric energy is greater than the input electric energy, and the key of the resonant circuit is the capacitor C2 in the circuit. Capacitor C2 must be able to meet the requirements of the withstand voltage and the maximum allowable current at any time and in any state of the loop.

[0367] Regarding the maximum withstand voltage value of the capacitor in this circuit and the maximum current passing through it, please refer to the tutorials or technical specifications of the AC circuit for the specific change rules.

[0368] When a single capacitor cannot meet the above requirements at the same time, multiple capacitors can be connected in series and then connected in parallel to form a capacitor array, and the capacitor array can be used to replace the capacitor in the circuit. The capacitor array can meet the above requirements at the same time.

Abstract

The invention discloses a transformer with output as a resonant loop. A secondary winding of a traditional transformer is directly connected with a load, and an end voltage of the secondary winding becomes an input voltage of the load. In the transformer with the output as the resonant loop, the output loop of the transformer is the resonant loop, a secondary winding L2 of the transformer is connected in series with a capacitor C2 and then is connected with a load ZR, and the loop is the resonant loop. The loop has inductive characteristic by selecting a capacitance value of the capacitor C2; since the capacitor C2 exists, the end voltage of the load ZR is higher than the end voltage of the secondary winding; and in the same condition, the output power of the transformer with the output as the resonant loop is higher than the output power of the traditional transformer, the output power of the transformer is higher than the input power, the output electric energy is higher than the input electric energy, and the electric energy can be provided for a device or a site requiring the electric energy.

Description

【Technical field】 [0001] A transformer outputting a resonant circuit is an improvement to a 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 kinds of alternating current waveforms, the alternating current passed through the power transformer is generally a simple harmonic alternating current. In this paper, the simple harmonic waveform alternating current is taken as an example for illustration. 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 ...
