A New Capacitor Transformer

Abstract

A new type of capacitor transformer, including four layers of primary conductive films, two levels of conductive films are arranged between adjacent two primary conductive films, and insulating dielectric layers are arranged between adjacent conductive films; one end of an odd number of primary conductive films is connected to a One end of the current-limiting insurance is connected, one end of the primary conductive film of the even layer is connected to one end of the other current-limiting insurance, and the other end of the two current-limiting insurances is connected to the power input terminal; the first layer, the fourth layer and the fifth layer The first-level conductive film is connected to one end of the resistor; the second, third and sixth-level conductive films are connected to the other end of the resistor, and the two contacts are respectively connected to the output end of the power supply. All devices are electrically sealed in Inside the electric field shielding layer, the surface of the electric field shielding layer wraps the shell. The capacitor transformer greatly reduces the manufacturing cost of the transformer, its own power consumption is very small, does not produce electromagnetic radiation, has low thermal effect, no impact voltage, short circuit is not easy to heat up and catch fire, large variable voltage range, small size, light weight, and wide application range .

Description

technical field [0001] The invention belongs to the technical field of basic electrical components, and relates to a transformer, in particular to a novel capacitance transformer. Background technique [0002] In electrical equipment and wireless circuits, transformers are often used for step-down voltage, matching impedance, safety isolation, etc. A capacitor transformer is a step-down circuit that works on the principle of capacitive voltage division. That is, a set of circuits is connected in series at the end of the power supply and in front of the electrical appliance to provide an appropriate voltage for the electrical appliance. This voltage transformation method has strict requirements on the size, specification, and quality of the capacitor, and there are positive and negative requirements for connecting to the power supply. Different power outputs require different designs, which are highly targeted and rarely used. [0003] The most widely used inductance coil ...
