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.
