Description
Technical Field
The invention relates to the field of high-voltage energy storage, in particular to a switch-capacitor integrated transformer primary module and an assembly method.
Background
With the development of pulse power technology, the demand on pulse power supplies is higher and higher. The traditional Tesla transformer generally adopts a series-parallel combination of a semiconductor switch and a capacitor bank as a primary energy storage based on the requirement of heavy frequency. However, this approach is limited to the semiconductor switch operating voltage and the capacitor storage, typically designed to be several hundred volts. In the occasion of needing output above megavolt level, the transformer transformation ratio is generally more than 2000: 1; the secondary charging time of the transformer is longer, generally dozens to hundreds of microseconds; the magnetic core has a large cross section and a heavy weight. In the technical field of electromagnetic pulse environment simulation, particularly for an electromagnetic pulse simulation device arranged in a maneuvering way, more severe requirements are put on the weight and the volume of a transformer. Therefore, it is desirable to increase the primary operating voltage of the transformer to reduce the transformer transformation ratio, and to decrease the inductance of the primary energy storage module to reduce the secondary charging time of the transformer, thereby reducing the voltage-second product requirement of the transformer and reducing the volume and weight of the transformer core.
According to the circuit analysis of the primary charging loop parameter of the transformer to the secondary output voltage, the charging time of the primary module inductor to the secondary voltage is positively correlated. The charge time on the secondary capacitor can be calculated using the following equation:
wherein Cp is a primary capacitor of the transformer; alpha is a detuning coefficient and is related to the inductance parameters of the primary and secondary capacitors of the transformer; l is ∑ The leakage inductance is mainly determined by the primary leakage inductance and the primary loop inductance of the transformer. Therefore, when the primary and secondary capacitance parameters and the transformer excitation parameter are constant, the primary loop inductance becomes L ∑ Is the main source of (1). Therefore, inductance parameters of the primary module of the Tesla transformer become main factors influencing secondary charging time and the product of volt-seconds of the transformer, and whether self inductance can be made smaller becomes a key influencing the weight of the magnetic core of the transformer.
The primary module of the Tesla transformer comprises a primary capacitor, a switch, a current measuring coil and the like. The traditional thought adopts the form of multi-switch and capacitor series-parallel horizontal arrangement, the stray inductance is larger, and the operating voltage is lower. Aiming at the primary of a transformer with operating voltage of dozens of kilovolts, the insulation requirement can be met only by long insulation distance of a capacitor and large switch gap, but the hidden danger of large inductance is brought to large volume.
In order to solve the problems, the invention provides a compact coaxial structure, a high-voltage capacitor, an open type gas switch and a current measuring coil are distributed, an integrated design of a capacitor, a switch and a load is adopted, and a transformer primary module which is more compact in structure and excellent in inductance and insulating performance and an assembling method are provided.
