State space techniques are employed to derive accurate models for buck, boost, and buck/boost converter power stages operating with and without zero-inductor-current dwell time. A generalized procedure is developed which treats the continuous-inductor-current mode without the dwell time as a special case of the discontinuous-current mode, when the dwell time vanishes. An abrupt change of system behavior...
A steady state analysis technique is described for a naturally commutated inverter in which the output voltage is undefined during part of each operating cycle. This technique is unique in that it requires the solution of only one first order differential equation and the matching of only one end condition. The solution is valid for any load configuration provided only that its harmonic impedances...
A method for modelling switching-converter power stages is developed, whose starting point is the unified state-space representation of the switched networks and whose end result is either a complete state-space description or its equivalent small-signal low<-f requency linear circuit model. A new canonical circuit model is proposed, whose fixed topology contains all the essential inputr-output...
State-plane analysis techniques are employed to study the voltage step-up energy-storage dc-to-dc converter. Within this framework, an example converter operating under the influence of a constant on-time and a constant frequency controller is examined. Qualitative insight gained through this approach is used to develop a conceptual free-running control law for the voltage step-up converter which...
