A Controller for Achieving Significant Increase in Output Power of Radiation Photovoltaic Cells

Micro nuclear batteries are devices that convert radioactive isotope decay energy into electrical energy. Thanks to the fact that radioactive isotope decay is not affected by the external environment, micro nuclear batteries have become a durable and indispensable energy solution in many application scenarios where traditional batteries are unable to cope or face challenges. However, due to the characteristics of the radiation volt effect isotope battery, its output power is relatively low. In this study, a micro energy harvesting controller was combined with a battery to achieve power pumping from 3mW to hundreds of watts, expanding the application scenarios of the radiation volt effect isotope battery and making it promising for use in ultra-high duty cycle mode loads.
