Control problem of a novel low-voltage DC converter.

Purpose – The purpose of this paper is to design the control for a new type of DC converter that can be used in low voltage and low power DC drives, e.g. in cars and robots. Design/methodology/approach – Based on the theory of the switching systems, the existence condition of the limit cycle for the novel DC/DC converter is formulated. Findings – The feed forward control which realizes the limit cycle is designed. The first experimental results show that the designed control of the DC/DC converter is effective in solving the control problem of DC drives and allows the use of a low input voltage as power source for the standard DC drive. Originality/value – Today DC/DC converters play a key role in power conversion and distribution. The presented DC/DC converter has a very simple circuit and allows changing the output voltage in the wide range that is needed for the DC drive control. [ABSTRACT FROM AUTHOR]
