Abstract
A method of producing an economical DC/DC converter that efficiently produces a relatively low output voltage and operates in a high ionizing radiation dose environment such as found in spacecraft and particle accelerator applications. That is, the converter comprises two P-channel FETs, a switching means for switching conductivity between the two P-channel FETs, and output means for outputting an output voltage. The output voltage being a step-down voltage that is unaffected by high-ionizing radiation such that is found in space or particle accelerators.
Claims18
A buck converter for producing relatively low output voltages comprising:
- input means for inputting an input voltage;
- a first P-channel FET;
- a second P-channel FET;
- switching means for switching conductivity between the first P-channel FET and the second P-channel FET;
- and
- output means for outputting an output voltage, said output voltage being a step-down voltage, whereby the output voltage is lower than the input voltage, and
- wherein the first P-channel FET, second P-channel FET and the output voltage are unaffected by high-ionizing radiation such that is found in space or particle accelerators.
A boost converter for producing voltages of negative polarity comprising:
- a first P-channel FET;
- a second P-channel FET;
- switching means for switching conductivity between the first P-channel FET and a second P-channel FET;
- and
- output means for outputting an output voltage, said output voltage being a step-up voltage, whereby the output voltage generated is of negative polarity, and
- wherein the first P-channel FET, the second P-channel FET and the output voltage are unaffected by high-ionizing radiation such that is found in space or particle accelerators.
