苏联科学家利用压电转换器代替电磁铁研制成一种微型变压器。这种转换器由两片连接成V形的压电陶瓷元件组成,其中一片作输入元件,另一片作输出元件。输入元件输入电流后就以输入电流的频率产生振动。这一振动传递到输出元件,它就产生共振,
Soviet scientists used piezoelectric transducers instead of electromagnets to develop a miniature transformer. This converter consists of two piezo-ceramic elements connected in a V-shape, one of which serves as the input element and the other as the output element. Enter the component input current to the input current frequency vibration. This vibration is transmitted to the output element and it resonates,
