Series-resonant and parallel-resonant circuits are used in induction heating. The terms describe the way the electrical current is running between the capacitor and the induction heating coil.
Series-resonant and parallel-resonant circuits are used in induction heating. The terms describe the way the electrical current is running between the capacitor and the induction heating coil.
The advantage of a parallel-resonant circuit is that it allows for long cable length between the capacitors and the induction heating power supply, 100-foot length or a 200-foot lengths are possible between the workhead and the induction heating power supply.
In a series-resonant circuit, longer lengths could cause so much energy loss that you would not be able to run the process effectively. However, this setup is relatively inexpensive to design and build, so for small power transfers, these types of setups are optimal.
For processes where you need to transmit power over long distances, parallel type setups are utilized.
