What is the output voltage of a flyback transformer?
A flyback transformer, also known as a line output transformer, comprises coupled inductors, making it unique from a typical transformer. It generates voltage from a few kilovolts up to 50 kilovolts with high-frequency currents from 17 kHz to 50 kHz.
How do you calculate flyback voltage?
The flyback voltage VOR is equal to VO (the secondary Vout plus the VF for the secondary diode D6) multiplied by the transformer winding ratio Np:Ns. Setting the flyback voltage VOR determines the winding ratio Np:Ns and the Duty ratio. The basic equation and an example are given below.
When would you use a flyback transformer?
Flyback transformers are used to provide voltage transformation and circuit isolation in flyback converters. Flyback transformers are the most popular choice for cost-effective, high-efficiency isolated power supply designs up to approximately 120 Watts.
What are the advantages of flyback converter over basic dc/dc converter?
Advantages of flyback converter
- The primary is isolated from the output.
- Capable of supplying multiple output voltages, all isolated from the primary.
- Ability to regulate the multiple output voltages with a single control.
- Can operate on a wide range of input voltages.
Does a flyback transformer output AC or DC?
In a flyback transformer, the primary winding need not be excited by AC voltage but can be excited even with a DC pulse input. The DC pulse input can be of low rating like 5 V or 12 V, which can be obtained even from a function generator. The DC voltage is converted to DC pulse with a rectifying circuit.
What is flyback voltage?
A “Flyback Voltage Spike” occurs when the supply current to an inductive load such as a solenoid is interrupted. They are inexpensive, sufficiently fast, and have a high enough reverse voltage and the current capacity needed for the application.
What is the function of flyback transformer?
A flyback transformers, also known as a line output transformer, stores energy from input voltage in switched-mode power supplies. It is useful for multiple electrical applications. At one time, these transformers were used to meet high voltage needs at high frequencies.
What causes flyback voltage?
A Flyback voltage or an Inductive Flyback is a voltage spike created by an inductor when its power supply is removed abruptly. The reason for this voltage spike is the fact that there cannot be an instant change to the current flowing through an Inductor.
