Output voltage controller for DC=DC converter - provides four specified control signals for four transistor switches in converter

摘要

The controller produces control signals (H,J) of variable duty factor, overlapping in time and second control signals (L,K). The first control signals control the transistor switches (Ts1, Ts2) in the converter in the lower region of the input voltage. The second control signals hold on the second transistor switches Ts3, Ts4). In the upper input voltage region, the first transistor switches are switched on by the first control signals of fixed duty factor. A variable control signal (L,K) is chosen for the second transistor switches.
