论述WB型直流电压变送器的工作原理、完成转换的各个模块电路的作用及变送器总电路的特点。
The work principle of the WB-type DC voltage transmitter, the functions of each conversion module and the characteristic of the whole circuit of the transmitter are elaborated in this paper.
随意地，如果用锗晶体管取代硅晶体管，可使模块工作的输入电压最小为0.25V。
Optionally, the modules can operate with input voltages as low as 0.25v if you replace the silicon transistors with germanium devices.
结果表明，所设计的直流开关型变换器集成模块输出电压稳定、纹波小、工作频率，高、功耗低，且体积小。
It has been shown that the designed DC switching mode converter has a stable output voltage frequency, small ripple, high operating frequency and low power consumption.
另外，由于补偿装置中igbt模块的额定工作电压的限制，若要将其运用于高压系统需要连接特殊的升压变压器，成本较高。
Otherwise, because of the limitation of IGBT's specified voltage, we must use special step-up transformer, which is more expensive, if we put this device into high voltage power system.
