Capacitor charging circuit and aviation obstruction lights

Abstract

The invention provides a capacitor charging circuit and an aviation obstruction beacon, and relates to the technical field of aviation obstruction beacons. The capacitor charging circuit comprises a voltage detecting circuit, a control chip, a sampling circuit, a voltage control circuit and a rectifying and filtering circuit, wherein the voltage detecting circuit detects an input voltage value ofa power source; the sampling circuit collects voltage value samples of capacitor groups in the rectifying and filtering circuit to acquire sampled voltage values; the control chip generates a controlsignal according to the input voltage value and the sampled voltage values; the voltage control circuit controls closing of corresponding relay contacts according to the control signal to acquire a corresponding supply voltage; the rectifying and filtering circuit rectifies and filters the supply voltage to supply power to load. The capacitor charging circuit has the advantages of large storage capacity, small size, low cost and long-term power supply, and can also meet the requirements of super-large current charging and discharging.

Description

technical field [0001] The invention relates to the technical field of aviation obstruction lights, in particular to a capacitor charging circuit and aviation obstruction lights. Background technique [0002] In order to prevent aerial vehicles from colliding with buildings, aviation obstruction lights that emit flashing signals are generally installed on the top of buildings such as high-rise buildings, TV towers, and communication towers to provide pilots with eye-catching signals to avoid obstacles. [0003] In recent years, with the breakthrough development of semiconductor lighting (LED) technology, the power of a single LED light source can reach more than 200W, the lighting speed is very fast, there is almost no delay, and continuous flashing has no impact on life, it has been successfully applied Used in walkway lights, spot lights, high-intensity signal lights, aviation obstruction lights and other fields. However, for aviation obstruction lights whose instantaneou...

AI Technical Summary

Problems solved by technology

However, for aviation obstruction lights whose instantaneous power exceeds 1kW and require high-current discharge pulses, a small power supply cannot meet the requirements, so it needs to be directly connected to the mains or equipped with a switching power supply, but this kind of power supply is large in size and high in cost
