Abstract
The invention provides an inverter circuit device for vehicles. The inverter circuit device is capable of converting a 12V direct current into a 220V/50Hz alternative current which is applicable to car audios, vehicle DVDs (digital video disks), vehicle refrigerators, notebooks, mobile phone chargers and various power supply adapters, and the inverter circuit device is simple in structure and low in manufacturing cost. The inverter circuit device comprises a square wave generating unit M1, a push-pull transformer M2 and an LC (inductor-capacitor) filter unit M3; and a vehicle-mounted storage battery supplies electric energy to the push-pull transformer M2, the square wave generating unit M1 supplies control signals to the field-effect transistor (Q1) of the push-pull transformer M2, the grid of a field-effect transistor (Q2) controls the push-pull transformer to generate electric energy with expected frequency and power to be supplied to the LC filter unit M3, and a voltage Vo is output from the output end of the LC filter unit.
Description
Affiliated technical field
The present invention relates to a kind of inverter circuit, related in particular to a kind of automobile-used inverter circuit device 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.
Summary of the invention
The object of the present invention is to provide a kind of automobile-used inverter circuit device of simple in structure and low in cost.
The present invention is for realizing that above-mentioned purpose adopts following technical scheme:
A kind of automobile-used inverter circuit device; It is characterized in that: its composition comprises square wave generating unit M1, push-pull transformer M2, LC filter unit M3; Vehicular accumulator cell is given push-pull transformer M2 with power delivery; The grid control push-pull transformer that square wave generating unit M1 flows to control signal FET Q1, the FET Q2 of push-pull transformer M2 produces the frequency of expection and the power delivery of size is given LC filter unit M3, LC filter unit output output voltage V o.
Beneficial effect of the present invention:
But the present invention can convert the 12V direct current into the alternating current of the 220V/50Hz of steam supply car sound equipment, automobile-used DVD, vehicle refrigerator, laptop computer, charger for mobile phone and the use of various power supply adaptor, and simple in structure, cheap for manufacturing cost.
