Control transformers and General transformer principle no difference. simply use different. Control transformer: a wide range of uses, boost, buck …Transformer works by using electromagnetic induction principle. Transformer has two sets of coils. Primary and secondary coils. Secondary coil outside the primary. When the primary link on AC, iron core in transformer produces alternating magnetic fields, secondary coil EMF. Transformer ratio is equal to the number of turns of the coil voltage ratio. For example: primary is 500 turns, secondary coil is 250 turns, primary general 220V alternating current, secondary voltage is 110V. Transformers can buck can boost.
Working principle of control transformer
Control transformer using electromagnetic induction principle, passed from one circuit to another circuit, an appliance is energy transfer power or transmission signal or signal transmission as an important component
Control transformer coil connected to the transformer and power supply, receives AC power, known as a coil winding connected to the load, send out for AC electrical energy meter, known as the secondary winding
A winding secondary winding of the voltage Phasor voltage Phasor U1 U2 line current Phasor I1 I2 electric potential in phase E1 electric potential in phase E2 N1 N2 turns chain a parallel turns, secondary windings for the amount of magnetic flux φ m, the magnetic flux is called the primary flux.
Use environment
Ambient temperature:-5 ° c to + 40 ° c, 24-hour average is less than + 35 ° c;
Installation site of no more than 2000M above sea level;
Air relative humidity in the ambient air temperature is + 40 ° c of not more than 50%, at a lower temperature can have a high relative humidity, the most humid months of the average monthly maximum temperature at 90%, and the monthly mean minimum temperature of + 25 ℃, and taking into account the products due to temperature changes occur on the surface of the gel.
A control transformer is needed in an electronic circuit that needs constant voltage, or constant current with a lower power, or even volt-amp rating. Generally, it is used together with other filtering devices-such as capacitors-to minimize the differences in the output. Hence, the result will be more constant current or voltage.
