A transformer is used with a rectifier to convert alternating-current electricity to direct current electricity. A simple transformer transfers the voltage and current from a higher-voltage supply to a lower-voltage supply. Transformers are used to transfer power to devices that do not include a built-in switching power supply such as a camera flash, or a lamp with an electronic dimming circuit. The permeability of many materials, including steel, aluminum, and ferrite core materials, is not constant but varies with the strength of the applied magnetic field. This is different from the ratio of the number of turns in the primary winding to the total number of turns in the primary and secondary windings. It is a non-linear function, and is related to the ratio of the product of the number of turns in the primary winding to the number of turns in the secondary winding. The magnetic permeability of a transformer is the ratio of the magnetic flux density in the core to the magnetic flux density in a vacuum. For variable inductances, transformers with variable inductors are used. ![]() Transformers can be used to transform AC to AC or AC to DC by series or parallel arrangements of multiple windings. A good quality factor can be achieved by winding a ferrite core with many turns to increase the magnetic field, or by the use of high-permability magnetic material. A lower quality factor means a higher proportion of the power is wasted in the form of heat rather than transferred to the load. A high-quality (short-circuit-safe) transformer should have a quality factor that is at least 1 million. It is related to the power dissipation of the transformer in the various sections of the circuit. The quality factor of a transformer is an important measure of its performance characteristics for most circuits. Higher voltages may be achieved by using a flyback converter and a transformer with a larger number of turns around the primary. A separate transformer is used to step down DC to lower voltages. One of the most common uses of transformers is to step down alternating current to direct current (DC). To accomplish this, the primary winding is stepped down with a variable-gain amplifier, and the secondary is stepped up with a high-impedance load. This is true even today for high-frequency sound systems. However, early vacuum-tube radios and high-frequency amplifiers used transformers with a much higher voltage rating than the mains. The majority of transformers are designed to operate at voltages close to mains. ![]() They are often used as part of a radio frequency (RF) system to process high-frequency signals. Transformers are used to step down or step up voltages, to alter the impedance of a circuit, or to provide isolation between otherwise isolated circuits. 1.2.3 Electrical Circuits Answer Key _TOP_ ![]()
