Abstract
The utility model provides a vehicle inverter circuit, capable of transforming a 12V DC into a 220V/50Hz AC which can be used by an automobile sound, vehicle DVD, vehicle refrigerator, a portable computer, a mobile phone charger and various power supply adapters. The vehicle inverter circuit is simple in structure and low in manufacture cost, and is composed of a square wave generation unit M1, a push-pull transformer M2 and an LC filtering unit M3. A vehicle storage battery transmits electric energy to the push-pull transformer M2, the square wave generation unit M1 transmits control signals to the grids of the first field effect transistor (Q1) and second field effect transistor (Q2)of the push-pull transformer M2 to control the push-pull transformer M2 to generate electric energy with expected frequency and size to thereby transmit to the LC filtering unit M3, and the output end of the LC filtering unit M3 outputs a voltage Vo.
Description
Technical field
The utility model relates to a kind of inverter circuit, has related in particular to a kind of vehicle-mounted inverter circuit that is used for using on the automobile.
Background technology
In recent years, Development of Power Electronic Technology is swift and violent, and inverter is widely used in fields such as daily life, computer, post and telecommunications, electric power system and Aero-Space.Automobile changes daily necessities into by the most original mode of riding instead of walk; Begun now by daily necessities to the aspect transition that enjoys life again; The electronic equipment that clan owning cars need use out of doors is more and more, for example automobile audio, automobile-used DVD, vehicle refrigerator, laptop computer, charger for mobile phone and various power supply adaptor.At the vehicle-mounted inverter of developed country is that each car is prerequisite.Vehicle-mounted inverter can change the 12V/24V direct current of automobile storage battery into most of electrical equipment needed 220V alternating current.Though vehicle-mounted inverter is also arranged at present, its complex structure, cost is high.
The utility model content
The purpose of the utility model is to provide a kind of vehicle-mounted inverter circuit of simple in structure and low in cost.
The utility model is for realizing that above-mentioned purpose adopts following technical scheme:
