Redundant power mixing element with fault detection for DC-to-DC converter |
摘要 |
<p>A power mixing apparatus for mixing current from a first and a second power rail includes a first enabling circuit to provide a first enabling signal, a second enabling circuit to provide a second enabling signal, a first inrush limiter to output a first current in response to the first enabling signal, a second inrush limiter to output a second current in response to the second enabling signal, a first open-circuiting circuit to decouple the first enabling circuit from the first inrush limiter when the first open-circuiting circuit is open-circuited, a second open-circuiting circuit to decouple the second enabling circuit from the second inrush limiter when the second open-circuiting circuit is open-circuited, a first isolation circuit to isolate the first inrush limiter from the second current, a second isolation circuit to isolate the second inrush limiter from the first current, and a direct-current converter to convert the first and the second current in response to the first enabling signal and in response to the second enabling signal. <MATH></p> |
