奥伦德OR-357PVG是一款独立的光隔离MOSFET驱动器。传统的MOSFET驱动器需要外部电源为驱动器本身提供VCC和/或VDD电源轨,而OR-357PVG则从隔离栅低压初级侧的LED电流获得驱动
本文使用的国产线性光耦ORPC817SC-C,隔离电压5kV等级,可满足电源提供可靠安全保障,符合国内、国际相关隔离击穿电压标准;电流传输比(CTR)为200-400%,输入1mA时输出端输出2~4mA,从而使光耦中的LED输出较小的工作电流来驱动,降低电路功耗,使电路系统能够正常稳定的输出;截止频率为80kHz,决定了光耦的工作频率不能超过这...

440 loans. The detailed descriptions and the descriptive statistics of the variables used in the empirical analyses are reported in Table1. In constructing the prudence index and misreporting variables, I focus on consumer loans, both current and mature. For the RR and LGD analysis, the empirical...
