摘　　要：单相半控发电机励磁,可替代励磁机,电抗分流,三次皆波等励磁方式。原理是取发电机单相电源引入励磁功率部分和调节器的工作电源。通过简单的模拟电路,实现测量,调差,给定,移相,脉冲放大,驱动可控硅,完成发电机的励磁自动调节,实现自动恒压,过速自动限压等综合功能。Single-phase and half controlled excitation system of the generator can replace the excitation source, reactance diffluence, cubic harmonic and other excitation methods. The principle is to connect the single-phase power supply of the generation with working power supply of the exciation frequency section and the regulator. Such a simple simulated power circuit can measure, adjust difference, transposition, magnify the impulse, drive the controllable silicon and automatically regulate the excitation of the generator, realize the automatic and constant pressure, and the automatic overdrive pressure limitation etc.
