At each voltage input, the DCDC will run for at least 10 minutes, and the temperature will be monitored with max temp being recorded
Voltage Input (Supply) | Current input (Supply) | Voltage output (Measured by 6*Vacross resistor) | Current output | Time | Temperature of Heat Sink | Notes |
---|---|---|---|---|---|---|
50 | It started faulting at this 50V input, so I just moved on to 70V. | |||||
70 (71) | 1.65 (1.72 initially) | 13.46 | 7.6132 | 10 | 86degreesC | It heated up a whole lot. I stopped it after 10 minutes, but that's because I noticed the resistors started melting the plastic box they were in. The temperature of the module itself was still steadily increasing (with no foreseeable stop) at about .1degreesC/sec. I need to find a better heat sinking method before testing will be continued. |

Due to the readings from testing at 70V, the testing has stopped and will be completed after placing a fan for heat sinking on top of the vicor module.
