Description
Technical Field
The invention relates to the field of high-voltage energy storage, in particular to a primary module of a transformer integrating a switch capacitor and an assembly method.
Background
With the development of pulse power technology, the requirements on a pulse power supply are higher and higher. The conventional Tesla transformer generally adopts a series-parallel combination of a semiconductor switch and a capacitor bank as primary energy storage based on the requirement of heavy frequency. However, this approach is limited by the semiconductor switching operating voltage and capacitor storage, typically a design voltage of a few hundred volts. In the case where outputs above megavoltage are required, the transformer transformation ratio is generally greater than 2000:1, a step of; leading to longer secondary charging times for transformers, typically tens to hundreds of microseconds; the magnetic core has a large section and a heavy weight. In the technical field of electromagnetic pulse environment simulation, particularly an electromagnetic pulse simulation device in motorized arrangement, more severe requirements are put on the weight and the volume of a transformer. Therefore, it is necessary to increase the primary operating voltage of the transformer to reduce the transformer transformation ratio, and to reduce the primary energy storage module inductance to reduce the secondary charging time of the transformer, thereby reducing the volt-second product requirement of the transformer and reducing the volume and weight of the transformer core.
Circuit analysis of the secondary output voltage according to the primary charging loop parameters of the transformer shows that the charging time of the primary module inductance to the secondary voltage is positively correlated. The charge time on the secondary capacitor can be calculated using the following formula:
wherein Cp is the primary capacitance of the transformer; alpha is a detuning coefficient and is related to the inductance parameter of the primary and secondary capacitors of the transformer; l (L) ∑ The leakage inductance is mainly determined by the primary leakage inductance of the transformer and the primary loop inductance. From this, the primary loop inductance becomes L when the primary and secondary capacitance parameters and the transformer excitation parameters are fixed ∑ Is the main source of (a). Therefore, the inductance parameter of the primary module of the Tesla transformer becomes a main factor affecting the secondary charging time and the volt-second product of the transformer, and whether the self inductance can be made smaller becomes a key affecting the weight of the magnetic core of the transformer.
The primary module of the Tesla transformer consists of a primary capacitor, a switch, a current measuring coil and the like. The traditional thinking adopts a mode of horizontally arranging a plurality of switches and capacitors in series-parallel connection, the stray inductance is larger, and the operation voltage is lower. Aiming at the primary of a transformer with the operating voltage of tens of kilovolts, the insulation requirement can be met only by long insulation distance of a capacitor and larger switch clearance, but the hidden trouble of large inductance is brought to a large volume.
Aiming at the problems, the invention provides a compact coaxial structure, a high-voltage capacitor, an open gas switch and a current measuring coil are arranged, and an integrated design of a capacitor, a switch and a load is adopted, so that the transformer primary module with more compact structure and excellent inductance and insulation performance and an assembly method are provided.
