Selection of intermediate frequency furnace pulse transformer

Selection of intermediate frequency furnace pulse transformer
The magnetic isolation device used in the trigger circuit is pulse transformer TM. I chose the KCB419/201ATM thyristor trigger transformer to play the role of the intermediate frequency furnace pulse transformer.
The intermediate frequency furnace pulse transformer is generally used in the switching power supply. Its function is the same as that of the ordinary transformer. It is to change the alternating current. The difference is that the ordinary transformer is transformed into a sine wave and the intermediate frequency furnace pulse transformer is transformed. A square wave with a certain or adjustable duty cycle (can be understood as a pulse signal), the PWM signal currently used is a pulse width modulation signal. The frequency conversion signal of the intermediate frequency furnace pulse transformer is much higher than the frequency of different power transformers, generally 10K-100KHZ, and the ordinary power transformer is 50HZ. Such an intermediate frequency furnace pulse transformer is much more efficient than an ordinary transformer.
KCB series thyristor trigger transformer features
1. Fully enclosed printed circuit board is directly soldered and installed.
2. Strong mechanical and environmental isolation, compact, sturdy, shock-resistant, moisture-proof and flame-retardant.
3. The electric strength between the windings is high.
4. The required ratio can be constructed to suit the triggering requirements.
5. Can be matched with all capacity thyristors.
6. Can be used as a common intermediate frequency furnace pulse transformer.
Application of KCB series thyristor trigger transformer
The trigger transformer is used in combination with the thyristor, and is usually connected between the control trigger unit and the thyristor control pole in the thyristor device, and transmits the trigger pulse on the one hand, and the reliable electrical connection between the strong and the weak on the other hand. The role of isolation.
