Представлены результаты исследования особенностей работы кинетического микрогенератора с пониженным выходным напряжением. Проведено сравнение эффективности работы многоступенчатого модифицированного удвоителя Беннета и системы, включающей двухступенчатый модифицированный удвоитель Беннета и диодно-конденсаторный делитель напряжения. Показано, что с увеличением числа ступеней в модифицированном удвоителе Беннета преобразование механической энергии в электрическую становится все менее эффективным. При этом для получения максимальной скорости накопления энергии предпочтительным является двухступенчатый усилитель мощности на основе удвоителя Беннета. Установлено, что при анализе работы диодно-конденсаторного делителя напряжения необходимо учитывать собственные емкости разрядных диодов, значительно влияющих на функционирование делителя. Обнаружены и проанализированы особенности поведения делителя при изменении сопротивления нагрузки и собственных емкостей разрядных диодов. Получены аналитические выражения, связывающие основные характеристики микрогенератора в целом с параметрами используемых электронных компонентов. Показано, что для расширения области «правильного» деления делителя необходимо использовать разрядные диоды с минимальными собственными емкостями, а также, что подключение к удвоителю Беннета нагрузки в виде делителя напряжения изменяет допустимую глубину модуляции емкости переменного конденсатора.

The results of the study of the kinetic microgenerator operation features with a re-duced output voltage are presented. A comparison of the performance of a multi-stage modified Bennet doubler and a system including a two-stage modified Bennet doubler and a diode-capacitor voltage divider is carried out. It is shown that with an increase of the number of stages in the modified Bennet doubler, the con-version of mechanical energy into electrical energy becomes less and less efficient. At the same time, in order to obtain the maximum rate of energy accumulation (power), a two-stage power amplifier based on a Bennet doubler is preferable. It is established that during analyzing the operation of a diode-capacitor voltage divider, it is necessary to take into account the intrinsic (reverse) capacitances of the discharging diodes, which significantly affect the operation of the divider. The features of the divider behavior depending the load resistance and the intrinsic capacitances of the discharge diodes are found and analyzed. Analytical expressions linking the main characteristics of the microgenerator as a whole with the parameters of the electronic components used are obtained. It is shown that in order to expand the range of the «correct» division of the divider, it is necessary to use discharging diodes with minimal intrinsic capacitances, as well as connecting a load to the Bennet doubler as a voltage divider changes the permissible capacitance modulation depth of the variable capacitor.
