本文介绍了新一代高精度空间矢量磁力计的新型自补偿激励电路的设计和实现。该应用从复杂的研究开始，包括设计非线性电感器的新稳健模型，从而研究最关键的点，然后设计自补偿励磁单元，最后以单元复杂的测试和磁力计的应用结束。励磁自补偿的应用将由传感器温度漂移（偏移漂移的主要来源）引起的磁力计偏移的温度漂移降低了 7 倍。
The paper presents design and implementation of the new self-compensating excitation circuitry to the new generation of high-precise space vector magnetometers. The application starts with complex study including design of new robust model of the non-linear inductor leading to investigation of the most crucial points, continuous by design of the self-compensating excitation unit and concludes with unit complex testing and application to the magnetometer. The application of the self-compensation of the excitation decreases temperature drift of the magnetometer offset caused by the temperature drift of the sensor (dominant source of the offset drift) by factor of 7.
