A concept of integral control is applied for multioperating point buck-derived pulse-width modulated dc-dc converters. A new large-signal circuit model of the power stage is introduced which allows for eliminating the load resistance from the system matrix. Two closed-loop continuous-conduction mode push-pull converters are designed using pole-placement technique: a conventional converter and a converter with a small inductor what is achievable by a bidirectional power flow. The large-signal dynamic performance of these converters is investigated by simulations in the time domain. The bidirectional power - flow converter with integral control was found to be suitable in switched load applications, e.g., radar systems, dot-matrix printers, and power supplies for random-access computer memories.
