The current feedback is considered as unavoidable part of all control system driving power electronic converters. However, if properly calculated volt-second balance is applied to input inductor, it is possible to eliminate the use of current sensor. Previously known solutions described in literature define only sensorless current control in discontinuous and continuous current mode. This paper contains explanation of various current trajectories that allows transition between different peak-to-peak values keeping inductor’s average current at a reference value. The analytical study of proposed solution is verified with simulation results.
