In recent years, with the promotion and use of new energy vehicles in the market, the number of users has grown rapidly.In order to meet the charging needs of tram users, Xishuangbanna Prefecture has accelerated the construction of charging infrastructure and has basically achieved full coverage of charging infrastructure in some transit highway service areas, urban areas and towns.Recently, reporters came to a charging pile site near Shangyinghaoting Community in urban Jinghong City. Yan Huanghan, a resident of Mannongfeng District, was charging his car. Yan Huanghan told reporters that he could travel 300 kilometers with 30 yuan of electricity. The charging speed is also very fast, and the cost is much lower than that of fuel vehicles.After visiting charging pile sites such as Zhiyuan Shangju Community and Shanghai Film Plaza, the reporter learned that most local residents and online ride-hailing drivers and other tram users believe that due to the charging speed, site environment, and electricity price of new energy vehicles, Considering factors such as discounts, charging at public charging piles is a more economical and affordable option.River

1. Definition and classification of switching power supply Switching power supply is a power supply method that uses high-frequency pulse width modulation (PWM) or high-frequency pulse frequency modulation (PFM) technology to convert AC voltage into low-voltage DC.Switching power supply is widely used in various electronic equipment due to its small size, light weight and high efficiency. It is an indispensable power supply method for the rapid development of today's electronic information industry.According to different output characteristics and functions, switching power supplies can be divided into the following categories: DC/DC converter: a switching power supply that converts one DC voltage to another DC voltage, commonly used in automobiles, aerospace, communications, etc. field.DC/AC inverter: A switching power supply that converts DC voltage into AC voltage. It is commonly used in solar photovoltaics, wind power generation, emergency lighting and other fields.AC/DC rectifier: A switching power supply that converts AC voltage into DC voltage. It is commonly used in computers.

RF inductors have a variety of uses and are available in a variety of construction types to meet the performance needs of a specific application.Matching, resonators, and chokes are common uses for inductors in RF circuits.Matching involves eliminating impedance mismatches and minimizing reflections and losses in lines between circuit blocks, such as antennas and radio frequency blocks or intermediate frequency (IF) blocks.Resonance is used in synthesizers and oscillator circuits to tune the circuit and set the desired frequency.When used as chokes, inductors can be placed in the power supply lines of functional components, such as RF blocks or IF blocks, with the purpose of attenuating high-frequency AC currents.The bias tee allows DC current to bias active devices such as diodes.The DC bias current and AC/RF signal are superimposed together and output from the AC+DC output port.Bias Tee Diagram RF Inductor Specifications Inductance is the property of an electrical conductor that resists changes in the current flowing through the conductor.It is the ratio of the induced voltage to the rate of change of the current that produces the induced voltage
