Abstract

The utility model relates to a micro AC power source transformer, which is an electric power converter and is composed of a transformation coil, a resistor, a capacitor and connection lines thereof, wherein, the resistor is connected in parallel with the capacitor and then connected in series with the transformation coil. The utility model has the advantages of small size, light weight, low cost and reliable work. The volume and the weight of electronic products can be reduced, and the service life can be increased.

Description

Miniature ac power transformer
Miniature ac power transformer described in the utility model is a kind of being widely used in the electric power conversion apparatus in power source performance is had relatively high expectations, electric current is less instrument, instrument, electromechanics, the household appliances.
At present, what generally use during instrument, instrument, electromechanics, household electrical appliances produce is the transformer that common instrument is made up of the transformation coil more, the poor-performing of this transformer frequency response and volume are bigger in small-power work, weight is big, bad adaptability, therefore it is little, in light weight to design a kind of volume, and the power transformer that cost is low is very necessary.
In view of above-mentioned existing in prior technology problem the purpose of this utility model is that a kind of volume of design is little, in light weight, cost is low, safe and reliable, high-performance micro ac power transformer that adaptability is good.
Miniature ac power transformer described in the utility model is characterized in that being made up of transformation coil, resistance, electric capacity and connection line thereof, and the primary coil of transformation coil is connected with resistance, and electric capacity is in parallel with resistance.
Miniature ac power transformer described in the utility model has fundamentally solved problems such as the existing volume of existing transformer is big, Heavy Weight, bad adaptability in small-power work, effectively for people provide a kind of volume little, lightweight novel transformer, the volume that can dwindle electronic product simultaneously greatly and weight and also can increase useful life of electronic product owing to the better performances of this product.
The new accompanying drawing of this practicality is: among the circuit diagram figure of miniature ac power transformer: L-transformation coil R-resistance C-electric capacity
Specific embodiment of the utility model is as shown in drawings: its structure is made up of transformation coil L, resistance R, capacitor C and connection line thereof, the elementary circle of transformation coil L is connected with resistance R, capacitor C is parallel to the two ends of resistance R, because the existence of resistance R and capacitor C, make the electric current and the pressure drop of primary coil all less, thereby can reduce the number of turn of transformation coil L greatly, reduce the volume and weight of transformation coil L simultaneously.
