| Abstract: | On the basis of the electromagnetic flowmeter, the traditional excitation system of the electromagnetic flowmeter is analyzed in this paper. The virtual peak voltage is discussed, which is originated from the lack of a good discharge circuit and has a negative impact on power. Thus, an improved H-bridge drive circuit control methodology is proposed, which can provide a good discharge circuit and improve the performance of the excitation system. |
