The cost and size of switched mode power supplies can be reduced by eliminating the measurement of inductor’s instantaneous current value. This paper discusses the implementation of current sensorless control algorithm for bidirectional half-bridge AC/DC converter that allows shaping inductor’s current without current sensor. The operation of half- bridge converter has been simplified to an equivalent single- switch model that simplifies implementation of a digital control system. The simulation results have confirmed the analytical assumptions and correctness of mathematical model.
