For the most common magnet systems charging voltages between 450V and 3000 are appropriate in order to achieve the pulse frequencies which are required.
Higher voltages are required when:
- The coil has a very high inductivity (e.g. big magnet systems)
- The magnetizing impulse shall be high frequency (short cycle times)
Low voltages are required when:
- Eddy current cause problems (e.g. massive iron parts)
- Insulations must be thin (e.g. sharp pole transitions)
- The coil has a very low inductivity (e.g. small multipole systems)
