摘 要：針對多線圈的振動發(fā)電機，分析了其不同模塊的不同聯(lián)接方式對輸出功率的影響，以及能夠輸出的最大功率。通過軟件仿真分析了在正弦激勵下，線圈串聯(lián)和混聯(lián)的輸出電動勢與最大輸出功率，并在頻率8 Hz、振幅8 mm 的正弦激勵下對樣機進行了實驗。對比實驗與仿真結(jié)果，其數(shù)值近似，波形變化規(guī)律相同，根據(jù)該研究，可以合理選擇振動發(fā)電機的聯(lián)接方式，來提高振動發(fā)電機的機電轉(zhuǎn)換效率。

Abstract: In allusion to the multi-winding vibration generator, this paper analyzed that the different connection modes of its different modules had impacts on the output power and the capable output of maximum output power. Through the simulation software, analysis was made to the output electromotive force and maximum output power of coils in series and parallel serial under sinusoidal excitation. A prototype was tested under the sinusoidal vibration with frequency 8 Hz and amplitude 8 mm. The experimental results compared with the simulation results, the former is close to the latter and they have the same waveform change rules. According to this research, the connection mode could be reasonably chosen for the vibration generator, to raise the electro-mechanical transformation efficiency for the vibration generator.
Key words: vibration generator; combination of coil; output electromotive force; output power
