This paper analyzes no-load voltage building process of a△-connected three-phase induction generator under single-phase operation.

Based on the theoretical analysis of each factor inducing vibration of core and winding, the experiments validated that the fundamental frequency magnitudes of core and winding vibrations are linear to square of no-load voltage and loading current respectively.

The analysis of uneven open circuit voltage of alkaline Zn/MnO_2 battery;

The cause of abnormal open circuit voltage of mercury-free alkaline Zn/MnO_2 battery;

An equivalent Coulombic efficiency was defined to alleviate these problems with an SOC estimation method combined with the open circuit voltage method,Kalman filter,and Ah counting method.

The influence of different resolvents and different counter electrodes to the deoxidize potential of I3- and the open-circuit voltage (VOC) of dye-sensitized solar cells (DSSC) were researched.

The open-circuit voltage and discharge performance of BCX and Li/SOCl_2 cells were compared and their cathode reaction characteristics were studied by CV curves.

The results show that the open-circuit voltage and EQE in high surface doping concentration cell are lower compared to the cells in low surface doping concentration.

Using fluorescent and incandescent as light source,basic features of solar cells such as short circuit current,open voltage,maximum output filling factor and so on were measured.
