High voltage power supply circuit with current detection function

Abstract

The invention discloses a high voltage power supply circuit with a current detection function; the features are that the high voltage power supply circuit comprises a transformer T1, an oscillation circuit, a current detection circuit, a resistor R7 with one end connected with a non-dotted terminal of a transformer T1 primary side inductance coil and the other end grounded, and a boost circuit respectively connected with the non-dotted terminal and the non-dotted terminal of a transformer T1 secondary side inductance coil. The high voltage power supply circuit is simple in structure and strongin practicality; the voltage system uses the oscillation circuit to fully convert the DC voltage outputted by a storage battery of an electric mosquito swatter into the AC voltage needed by the transformer, thus enabling the transformer to output more stable voltage; in addition, the transformer is combined with the boost circuit, thus effectively ensuring a work voltage of 1500 KV for the electric mosquito swatter, ensuring the circuit to output a more stable high voltage, and greatly improving the mosquito eradication effect of the electric mosquito swatter.

Description

technical field [0001] The invention relates to a power supply circuit, in particular to a high-voltage power supply circuit with a current detection function. Background technique [0002] With the continuous development of social and economic construction, a large amount of domestic waste and construction waste have caused more serious pollution to our living environment, causing mosquitoes to multiply in large numbers, seriously affecting our health. In order to eliminate the harm of mosquitoes to us, people have adopted different methods to eliminate mosquitoes. At present, we mostly use mosquito coils, insecticides and electric mosquito swatters to prevent mosquitoes from invading. Among them, we mostly use electric mosquito swatters to kill mosquitoes. insect. However, the booster power supply of the existing electric mosquito swatter has the problem of unstable output voltage, which leads to the inability of the electric mosquito swatter to effectively electrocute th...
