Energy conversion technology of gallium nitride rectifier bridge for air-induced acoustic piezoelectric generator

In order to meet the power generation performance requirements of low-power power supplies and improve the energy collection efficiency of the new power supply airflow-induced acoustic piezoelectric generators, domestic GaN rectifier diodes are applied to low-power circuits, and the low dropout voltage of the airflow-induced acoustic piezoelectric generator power supply circuit has been developed. Gallium nitride (GaN) rectifier bridge, designed a low-dropout gallium nitride (GaN) rectifier bridge energy harvesting circuit. The static and dynamic experimental tests show that the domestic GaN rectification scheme can realize the dynamic rectification of the air-induced acoustic piezoelectric generator, with lower circuit loss, and can meet the domestic demand for low-power power supplies.
