A magnetically regulated D-C to D-C converter power supply

In situations where a single d-c source only is available or desirable to power electronic equipment requiring a number of different and isolated supply voltages, a so-called d-c to d-c converter1¿3 can be used. A typical example of this situation is found with mobile equipment where space and weight considerations determine the available power source. Communication equipment having buffer batteries to maintain continuous operation, which are unaffected by interruptions of the primary power source, is another example.
