Were newly developed gas flow induced acoustic piezoelectric power generator compressor hair verification test results verify the pressure chamber bottom stream induced by acoustic resonance in the acoustic excitation of the piezoelectric transducer, the open circuit voltage, a matched load, the displacement of the piezoelectric vibrator same frequency, with the increase of the gas flow inflow velocity, acoustic pressure, displacement of the piezoelectric vibrator increases. On this basis, the production of low pressure difference gallium nitride (GaN) synchronous rectifier bridge passive energy harvesting circuit is connected in parallel directly to the generator magnetic seat, a sound pressure induced airflow generator power side. By static and dynamic comparative test results show that a low pressure difference gallium nitride (GaN) higher than the output power of the rectifier bridge ordinary bridge rectifying Schottky SR560 75% or more, the conversion efficiency of the low pressure differential is a gallium nitride (GaN) is more rectifier bridge high.

A newly developed air compressor blow-off power generation verification test for air-to-acoustic electro-electric generators was carried out, and the results verified that the voltage converter under the acoustic ally of the airflow generated under the resonance cavity of the acoustic pressure, open-circuit voltage, matching load, piezoelectric vibrator displacement frequency is consistent, with the increase of the gas flow speed, the acoustic pressure, piezoelectric vibration displacement also increased. On this basis, the passive synchronous energy acquisition circuit of the low-pressure differential nitride (GaN) rectifier rectifier will be connected directly and sideby to the magnetic rear-seat generator and the power-side of the airflow-induced acoustic piezoelectric generator. Through static and dynamic comparison test, the results show that the output power of the low-pressure differential nitride (GaN) rectifier (GaN) rectifier bridge is more than 75% higher than that of the ordinary Schottky SR560 rectifier bridge, and the conversion efficiency of the low-pressure differential nitride (GaN) rectifier (GaN) rectifier is higher.

The results show that the sound pressure, open circuit voltage, matching load and displacement frequency of piezoelectric vibrator at the bottom of the resonant cavity of piezoelectric transducer excited by air induced sound are the same. With the increase of air inflow speed, the displacement of sound pressure and piezoelectric vibrator also increases. On this basis, the passive synchronous energy acquisition circuit of the low-voltage gap rectifier bridge is directly connected in parallel to the power supply side of the magnetic recoil generator and the air induced piezoelectric generator. The results of static and dynamic tests show that the output power of the low-voltage differential Gan bridge is 75% higher than that of the Schottky sr560 bridge, and the conversion efficiency of the low-voltage differential Gan bridge is higher.<br>
