摘要
针对多线圈的振动发电机,分析了其不同模块的不同联接方式对输出功率的影响,以及能够输出的最大功率。通过软件仿真分析了在正弦激励下,线圈串联和混联的输出电动势与最大输出功率,并在频率8 Hz、振幅8 mm的正弦激励下对样机进行了实验。对比实验与仿真结果,其数值近似,波形变化规律相同,根据该研究,可以合理选择振动发电机的联接方式,来提高振动发电机的机电转换效率。
In allusion to the multi-winding vibration generator, this paper analyzed that the different connection modes of its different moduleshad impacts on the output power and the capable output of maximum output power. Through the simulation software, analysis was made to theoutput electromotive force and maximum output power of coils in series and parallel serial under sinusoidal excitation. A prototype was testedunder the sinusoidal vibration with frequency 8 Hz and amplitude 8 mm. The experimental results compared with the simulation results, theformer is close to the latter and they have the same waveform change rules. According to this research, the connection mode could be reasonablychosen for the vibration generator, to raise the electro-mechanical transformation efficiency for the vibration generator.
