Abstract
Developing a high-performance transducer driver is essential yet challenging for air-coupled ultrasound applications. This study introduces a MOSFET-based bipolar high-voltage pulse driver designed for defect detection in soft-pack lithium batteries. High-voltage DC generation is achieved through a push–pull inverter and full-wave voltage multiplier circuit, producing a stable DC output. High-speed MOSFET switching then controls the charging and discharging of a capacitor in an RC network, generating a symmetric bipolar high-voltage pulse signal with a peak-to-peak voltage of 1104 V at 100 kHz. Performance evaluation experiments demonstrated that a 7-cycle pulse train provides an optimal balance of signal penetration and time resolution, effectively preventing waveform overlap. The system reliably penetrates soft-pack lithium batteries up to 6 mm thick, and detects internal lithium battery defects, such as 1 mm air bubbles. Overall, this bipolar high-voltage pulse driver surpasses traditional designs in both time and frequency domains, offering enhanced detection accuracy and practicality for air-coupled ultrasonic inspection of lithium battery defects.
