Question: Do you make space-level multipliers?
Answer: We have manufactured many standard multipliers for space projects. Typically JANTXV level diodes are up-screened to space level, and additional testing and source inspections performed on the final assemblies. View a list of space projects VMI has contributed to.
Question: Will a multiplier work at an operating frequency of 60Hz?
Answer: No. Most multipliers work best between 25KHz and 150KHz. There are exceptions to the rule, but generally the absolute minimum operating frequency is 10KHz.
Operating frequency directly impacts
- Ripple voltage (the higher the operating frequency, the lower the ripple voltage)
- Regulation voltage (the higher the operating frequency, the less drop in output voltage at load)
Question: How does temperature effect the output of the MVM302P08 hybrid multiplier?
Answer: Keeping all things constant, the output voltage decreases as the temperature increases. There is a significant drop-off at temperatures higher than 150C. Other factors effecting output voltage include load current and operating frequency.
Other hyrid families exhibit the same phenomena. The actual output voltage varies depending partly on the number of stages and input voltage. Other factors include operating frequency, output current, and type of load.
Question: Do the MVM series multipliers come in a negative Vout version?
Answer: The MVM series can be used to generate either a positive or negative output voltage.
- To get a negative output voltage from the MVM type series, connect your input signal to V2. The HV output will be V1, and the output voltage will be negative.
