A unique kind of electrical transformer is a flyback transformer, also known as a line output transformer. It was initially intended to produce relatively high frequency, high voltage sawtooth signals. It is widely utilized in switched-mode power supplies for both low and high-voltage supply in contemporary applications.
A switch from a DC supply powers the flyback transformer’s primary winding. The principal inductance causes the current to ramp up when the switch is turned on. The secondary winding is coupled in series with an integrated diode, which prevents the secondary current from forming and eventually opposing the primary current ramp.
As the magnetic field in the core falls, the energy held in the magnetic core is released to the secondary. The output winding’s voltage increases dramatically until the load conditions put a cap on it.
The charge flow takes the form of a descending ramp once the voltage reaches a level that permits a secondary current. Repeating the cycle is then possible. The transformer is considered to operate in discontinuous mode if the secondary current is allowed to decrease to zero.
Continuous mode is present when the secondary current is consistently non-zero. Particularly about power supply transformers, this word is employed. Devices using CRT displays, such as televisions and CRT computer monitors, operate via flyback transformers. Depending on the gadget, the voltage and frequency can vary on a broad scale.
Large color TV CRTs, for instance, could need 20 to 50 kV with a horizontal scan rate of 15.734 kHz for NTSC devices and 15.625 kHz for PAL systems. In contrast to a power transformer, which utilizes an alternating current of 50 or 60 hertz, a flyback transformer often operates with switched currents at significantly higher frequencies, in the range of 15 kHz to 50 kHz.
The Global Flyback transformer market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The launch of the Flyback Transformer Selector in the most recent version of the REDEXPERT tool by Wurth Electronics. The Smart Transformer Selector has undergone a complete redesign with its incorporation into REDEXPERT.
This free utility doesn’t require login and is accessible in seven different languages. The REDEXPERT tool offers additional possibilities, such as performance simulation, filter settings for more than 20 mechanical and electrical characteristics, direct access to product datasheets, and direct free sampling. The Smart Transformer Selector, the original transformer selection tool, will be accessible through the end of the year before being switched to the REDEXPERT version.
