“…The voltage derating factor is 60% (Class-II). Thick-film hybrid integrated circuit (TF-HIC) process [26]- [28] installs passive components and bare integrated chips (die) on the substrate with screen-printed conductors and resistors, then connecting components and conductors with wire bonding. TF-HIC process is flexible and has good heat dissipation performance; bare chips avoid the reliability problems caused by the package.…”

In high-reliability applications, DC/DC converters should realize high-efficiency and fasttransient in harsh environments. Thus, the circuit parameter design and the reliability design are both critical. The secondary-side control circuit has a faster transient and a simpler gate-drive than the primaryside control circuit, which has been used for over twenty years. However, the detailed design procedure and analysis of the high-reliability secondary-side control circuit have not been presented in the literature. This paper introduces a secondary-side control circuit design and its small-signal modeling procedure with a peak-current-mode-control (PCMC) forward converter. The reliability design and evaluation for thick-film converter are demonstrated. A 100-watt prototype is manufactured, and its steady-state waveforms and transient waveforms are tested and then compared with other high-reliability products. The experimental results show that the peak efficiency reaches 90.6%; the load transient response is 330mV/560μs; and the mean-time-between-failure (MTBF) value is 481 kilo-hours, proving the fast-transient and high-reliability features of the secondary-side control circuit.INDEX TERMS High-reliability, secondary-side control, bias-power supply, peak-current-mode-control, small-signal modeling, thick-film process, high transient.

“…Resonant topologies [25][26][27][28][29][30][31] exhibit other advantages for this application. They present two main properties: the capability of transferring power to the microvalve and the possibility of combining the power signal and the control one, the latter determining which valve should be activated.…”
