“…The operation of electrostatic MEMC is based on a change of the variable capacitor capacitance under the influence of external mechanical oscillations (vibrations) [4,7]. In order to transfer the electrical energy obtained using the MEMC to the load, the converter is combined with the corresponding electrical circuits (conditioning or interface circuits) [8][9][10][11][12][13]. Such a system as a whole is called as microelectromechanical generator (MEMG).…”

The simulation results of the voltage divider operation based on switchable capacitors with diode switching for electrostatic microelectromechanical (MEM) generators are presented. It has been established that for the divider with diode-switched capacitors, the voltage dividing coefficient is not remain the same when the load resistance changes, and for higher load resistances, the load voltage asymptotically approaches the value of the power source. Analytical expressions have been obtained for estimating the parameters of the divider with diode switching, which allow evaluating its characteristics at the preliminary stage of the MEM generator design. It has been shown that the simulation of the diode-capacitor voltage divider operation has to be carried out taking into account the dynamic volt-ampere characteristics of diodes.
