“…For these reasons, most commercial PWM control ICs use current mode control and not voltage mode control. Dynamic analysis of the AHB has been presented in [2], [4] and [6]. However, in [2] and [4] the analysis is only presented for voltage mode control.…”

“…Furthermore, only in [6] is any consideration given to the effects of using unbalanced turns aside from an arbitrary mathematical derivation where N S1 ≠N S2 . However, the work presented in [6] only discusses the effect of unbalanced turns on the small signal dynamics under voltage mode control. Under peak current mode control, the dynamic behaviour differs significantly.…”

“…However, in [2] and [4] the analysis is only presented for voltage mode control. In [6], the emphasis is voltage mode control, however one short section is included documenting the dynamic properties of the AHB with balanced transformer turns under current mode control. Unfortunately, results are not presented for unbalanced transformer turns under current mode control.…”

“…In addition to the advantages mentioned above, the transformer secondary turns can be unbalanced to further minimize the output filter size. Unfortunately, in all of the literature [1]- [10], except for [2], [6], [7], [9] and [10] the analysis was carried out with balanced secondary turns, N S1 =N S2 . Furthermore, only in [6] is any consideration given to the effects of using unbalanced turns aside from an arbitrary mathematical derivation where N S1 ≠N S2 .…”

An overall study of the Asymmetrical Half-Bridge (AHB) with unbalanced transformer turns under current mode control is presented. An analysis is presented for the output filter, switch stress, and dynamics. In addition, key ideas of the AHB transformer design are presented. This is followed by a survey of the existing methods that the AHB uses to achieve zero voltage switching at turn-on, namely the series inductance method and the parallel inductance method. Following these, the auxiliary L-C-C circuit method is proposed for the AHB to further minimize switching loss. Experimental results are included for a 48V/5V prototype operating at 6A load and 400kHz.

A dual modulation control scheme is employed to generate two tightly controlled output voltages in an asymmetrical half-bridge PWM converter. The main output is controlled via duty ratio modulation while the second output via frequency modulation. Such a combination provides a costeffective circuit with an optimal balance between operating frequency (thus size of magnetic components) and efficiency. In this paper, the circuit operation of the converter is described and its small signal behaviors analyzed. Design constraints due to frequency-dependent nature of the power stage and some practical design considerations are also discussed.
