Abstract: A DC-to-DC converter is disclosed that uses a relay coil as an inductor. A relay has a coil and an associated relay contact. When the coil is energized, the contact closes and connects a first DC voltage signal to an electrical load. The coil is periodically energized and de-energized. The duration of de-energization is less than that necessary to permit the contact to open. The periodic energization and de-energization of the coil results in voltage values being developed across the coil. A rectifying diode is used to electrically couple the coil to a storage capacitor. The voltage developed across the storage capacitor provides a second DC voltage signal having a value greater than the first DC voltage signal relative to a common reference.
