The asynchronous motor test bench has a simple structure, easy manufacturing, use, and maintenance, reliable operation, light weight, and low cost. Therefore, it is widely used in various types of motors and has a high demand. About 90% of the various transmission devices of asynchronous motors are driven by asynchronous motors, accounting for about 60% of the total load in the power grid. To meet the matching requirements of various mechanical equipment, there are a large number of asynchronous motor varieties and specifications. Next, the asynchronous motor test bench editor will introduce the relevant knowledge of high-voltage DC power supply to you.
High voltage direct current power supply is widely used in daily production and life, especially in military, medical, insulation testing and other fields with frequent applications. Conventional high-voltage direct current power supplies often use linear power supply technology, which results in low overall efficiency, average performance, large size, and heavy weight of the power supply. With the advancement and development of switching power supply technology, more and more DC power supplies for various purposes are adopting switching power supply technology. As a characteristic and advantage of linear power supply, power on/off has become the mainstream form in the power supply industry. Switching power supply technology has been adopted in the field of HVDC power supply, which makes high-voltage DC power supply have the advantages of small size, light weight, high efficiency, and good performance. The research work of this article is aimed at designing the high-voltage power supply required for X-ray generating equipment. This article first introduces the current development status of the high-voltage direct current power supply field, as well as the basic principles of X-ray tube operation. It demonstrates the topology structure of various types of switching power supply main circuits. Due to the difficulty of a single structure of the converter to meet the requirements of system function and performance indicators, a combined structure of a half bridge converter combined with a step-down chopper circuit main circuit structure is proposed. Subsequently, the paper conducted specific calculations on the parameters of the main components in the main circuit, designed the key high-voltage transformer in the converter, and identified the key factors and solutions that affect the manufacturing performance indicators of the transformer.
