All power processors presented so far carry a common trait; the output voltage is less than the input, that is step–down. However, in many occasions, the inputs are low voltage battery sources, but outputs higher than the source are needed. In this chapter, topology specifically configured to act in step–up fashion is covered. Voltage-mode control has been first presented.
Like flyback configuration, boost converters operating in DCM invite less trouble in designing control strategy. The rationale opting for DCM has also been examined in this chapter.
