“…Moreover, in these schemes, the switching frequency of the power semiconductor devices is held constant, which is an added advantage for medium-and high-power applications. However, the schemes based on OCC exhibit instability in operation when the magnitude of the load current falls below a certain level or when the converter is operating in the inverting mode of operation [5], [16]- [19], [29].…”

“…Generally, this information is obtained by employing either a phase-locked loop (PLL) or a current phase observer digital technique [9]- [15]. To simplify the control structure of these grid-connected systems, one-cycle-control (OCC) based ac-to-dc converters have been proposed [5]- [7], [16]- [20]. This control technique does not require the service of the PLL.…”

Abstract-AC-to-DC converters based on one-cycle control exhibit instability in current control at light load conditions as well as when they are operating in the inverting mode. In this paper, a modified one-cycle controller for bidirectional ac-to-dc converter is proposed. A fictitious current component in phase with the utility voltage is synthesized. The sum of this current component and the actual load current is compared with the sawtooth waveform to generate the gating pulses for the switches. This modification not only renders stability to the converter at light load conditions and the inverting mode of operations but also enables the converter to seamlessly transfer its operation from the rectifying mode to the inverting mode and vice versa. Detailed simulation studies are carried out to verify the effectiveness of the proposed scheme. To validate the viability of the scheme, detailed experimental studies are carried out on a 2-kW laboratory prototype.Index Terms-Bidirectional ac-to-dc converter, high-powerfactor converter, improved light load stability, one-cycle control (OCC).

One-cycle-controlled ac-to-dc converters exhibit instability in current control at light load conditions and while they try to operate in the inverting mode. A one-cycle control (OCC)-based scheme has been reported in the literature which overcomes the aforementioned limitation. However, the controller for the scheme presented in the literature needs to sense instantaneous phase voltages of the utility. In an effort to dispense with the voltage sensors of the OCC-based bidirectional converter, a voltage-sensorless one-cycle-controlled bidirectional ac-to-dc converter is proposed in this study wherein the information regarding the instantaneous utility voltages are synthesised within the controller and hence they are not required to be sensed. Instantaneous phase voltages of the utility are reconstructed by filtering pertinent switching sequences (gate pulses) of the converter through second-order band-pass filters. Rigorous analysis of the proposed scheme is carried out. Detailed simulation studies are carried out to demonstrate efficacy of the proposed scheme. In order to verify the viability of the scheme detailed experimental studies are carried out on a laboratory prototype developed for the purpose.
