Abstract:
This paper presents an optimization approach for external components in automotive auxiliary inverter solutions utilizing the ONSEMI Automotive Smart Power Module (ASPM) series, particularly focusing on E-compressor applications. External component selection is critical for eliminating specific abnormal operations, such as drive IC latch issues in junction-isolated type HVIC. The study addresses one such drive IC latch malfunction problem and proposes methods to mitigate it using external components such as VDD and VBS capacitors, bootstrap resistors.
