Backup power supply voltage regulation circuit used for construction

Abstract

The invention discloses a backup power supply voltage regulation circuit used for construction. The backup power supply voltage regulation circuit comprises a photovoltaic conversion circuit, an undervoltage detection switching circuit, a high-frequency oscillator and a voltage regulation circuit; the photovoltaic conversion circuit is connected with the undervoltage detection switching circuit, the high-frequency oscillator and the voltage regulation circuit; the undervoltage detection switching circuit is also connected with an energy-storage storage battery E; and the high-frequency oscillator is also connected with the voltage regulation circuit. The backup power supply voltage regulation circuit used for construction disclosed in the invention can perform photoelectric conversion by asolar panel for supplying electric energy, and can carry out electric energy storage through the energy-storage storage battery; by virtue of an additional electric quantity detection part circuit, an over-discharge condition can be prevented; a voltage boosting part adopts an oscillation voltage boosting manner, so that a voltage boosting chip structure is omitted; and by adopting a conventionalelectronic element connecting method, the manufacturing cost is lowered, output diversification can be realized, and different power utilization requirements can be satisfied, so that the backup power supply voltage regulation circuit has the advantages of low cost, convenience in use and wide use range.

Description

technical field [0001] The invention relates to a standby power supply, in particular to a voltage regulating circuit of a standby power supply for construction. Background technique [0002] With the continuous development of my country's electric power industry, electric power has become the most important energy source in people's production and life, and will replace non-renewable resources such as oil and natural gas in the future. Therefore, electric power equipment has become an indispensable part of life, especially In production and manufacturing, DC voltage is widely used in electrical construction technology due to its advantages of high stability and small fluctuations. This type of power device requires a stable DC power supply, especially when laying AC power supply lines during outdoor construction. It is very inconvenient, and for some high-current electrical loads, a higher voltage is required to drive. At this time, a larger mobile power supply is required to...

[0002] With the continuous development of my country's electric power industry, electric power has become the most important energy source in people's production and life, and will replace non-renewable resources such as oil and natural gas in the future. Therefore, electric power equipment has become an indispensable part of life, especially In production and manufacturing, DC voltage is widely used in electrical construction technology due to its advantages of high stability and small fluctuations. This type of power device requires a stable DC power supply, especially when laying AC power supply lines during outdoor construction. It is very inconvenient, and for some high-current electric loads, a higher voltage is required to drive. At this time, a larger mobile power supply is required to supply, and the large-volume mobile power supply is inconvenient to move, so there are certain defects
