In the world of electronics and electrical engineering, power supply units play a crucial role. Without a stable and reliable power supply, electronic devices cannot function properly. Among various types of power supply units, AC to AC power supply proves to be an essential one.
AC to AC power supply, also known as alternating current to alternating current power supply, is a type of power supply that converts the input AC voltage, frequency, and waveform into a different AC voltage, frequency, and waveform. This type of power supply is used in various electronic devices, including radio receivers, audio amplifiers, and other electrical equipment.
In this blog, we will dive into the details of AC to AC power supply, including its working principle, types, applications, and advantages.
Working of AC to AC Power Supply:
The working principle of AC to AC power supply is based on the transformer's operation, which is an essential component of the unit. The transformer consists of two coils, primary and secondary, having different numbers of turns. The input voltage is applied to the primary coil, which induces a magnetic field, and the secondary coil is connected to the load.
When the AC voltage is applied to the primary coil, the magnetic field varies with the input frequency, inducing an AC voltage in the secondary coil with a different value of voltage, frequency, and waveform. By adjusting the number of turns in the primary and secondary coils, the output voltage and frequency can be controlled.
