Title:
圧電ポンプの駆動システム
Document Type and Number:
Japanese Patent JP6617129
Kind Code:
B2
Abstract:
A driving system (10) includes a voltage conversion module (11), a frequency control module (12), a voltage switching module (13) and a detecting module (14). The voltage conversion module (11) is used for converting a first DC voltage (Vd1) into a second DC voltage (Vd2). The frequency control module (12) searches a resonant working frequency of a piezoelectric actuator (161) through circuit oscillation and generates a switching signal according to the resonant working frequency. According to the switching signal, the voltage switching module (13) converts the second DC voltage (Vd2) into an AC voltage so as to drive the piezoelectric actuator (161). The detecting module (14) includes a gas pressure sensor (141) and a microcontroller (142). The gas pressure sensor (141) generates a detected gas pressure value according to a result of detecting a gas pressure of the piezoelectric pump (16). The microcontroller (142) controls the voltage conversion module (11) to adjust the output voltage. Consequently, the gas pressure of the piezoelectric pump (16) is adjusted.
