Pole coil excitation adjusting device, pole coil excitation adjusting system and pole coil system

The invention relates to a pole coil excitation adjusting device, a pole coil excitation adjusting system and a pole coil system, the pole coil excitation adjusting device comprises a rectifier, a single-phase inverter and a controller, the rectifier can convert the electricity of an external power supply into direct current, and the single-phase inverter is connected with the controller. Then thevoltage of the external power supply is increased to multiple times through the single-phase inverter, and the capacity of the excitation source provided for the pole coil is greatly improved under the condition that the current is constant. By arranging the rectifier, the single-phase inverter and the controller, the technical problems that in the prior art, the power supply capacity of an existing engineering system is generally low, and normal operation of a pole coil test cannot be guaranteed are solved, and the technical effect of improving the capacity of a pole coil excitation source is achieved. 本申请涉及一种磁极线圈激励
