| Abstract: | With the rapid development of domestic DC-DC hybrid power supply products, their lifetime becomes much long. How to evaluate the lifetime quickly and accurately becomes an important and critical problem. As the key components of the DC-DC hybrid power supply, the ceramic capacitors and thick film resistors are most prone to failure to decrease the DC-DC hybrid power supply lifetime. The actual failure rates of ceramic capacitors and thick film resistors were obtained by acceleration lifetime test. Then the accurate lifetime information of the DC-DC hybrid power supply was obtained through the method of reliability prediction. |
