“…Therefore, the topology can be modelled as two independent boost converters interleaved with a 180 degrees phase-shift and galvanic isolation. This fact, will have an impact on the EMI input filter as has been reported in [26] for interleaved boost converters.…”

Abstract-A single-stage, AC/DC driver for High Brightness Light-Emitting Diodes (HB-LED) with galvanic isolation is presented in this paper. The driver is based on a Dual Inductor Current-fed Push-Pull (DICPP) converter with each inductor operating in Boundary Conduction Mode (BCM). The interleaving between the two inductors makes possible for the converter to reduce the high input current ripple of a BCM. Moreover, it is fully compliant with IEC 1000-3-2 Class C, and it is also able to achieve high Power Factor (PF). Moreover, the low component count, simplicity and overall outstanding characteristics make this topology suitable for medium power range HB-LED drivers in low cost applications.Finally, the proposed topology has been tested on a 90W prototype for the full range of the US single-phase line voltage, feeding several strings of HB-LED, with an output voltage of 48V at full load. The prototype achieves a maximum efficiency of 92% with 0.99 power factor, 8% THD at full load and guarantees good quality light.

This paper presents a comparison between the performances of different interleaving control methods for gallium-nitride (GaN) devices based MHz critical conduction mode (CRM) totem-pole power factor correction (PFC) circuit. Both closed-loop interleaving and open-loop interleaving are good for the 70 kHz CRM PFC; but for a MHz frequency CRM PFC with microcontroller (MCU) implementation, openloop interleaving outperforms closed-loop interleaving with only a small and non-amplified phase error. After software optimization, the phase error of the open-loop interleaving is smaller than 3 degree at 1MHz, when the control is implemented by a 60 MHz low cost MCU. Significant ripple cancellation effect and differential-mode (DM) filter size reduction is achieved with good interleaving. For a 1.2 kW MHz totem-pole PFC, the DM filter size is reduced to one quarter when compared to the counterpart of a 100 kHz PFC. Last but not least, the stability of the open-loop interleaving is also analyzed indicating that the MHz CRM totem-pole PFC with voltage-mode control, open-loop interleaving, and turn-on instant synchronization can maintain critical mode operation with better stability compared to the 70 kHz CRM PFC.

“…This paper uses a mathematical model based on the work presented in [5], [6] to calculate the quasi peak conducted EMI noise under boundary and continuous conduction mode operation for a conventional single phase PFC, as shown in Fig 3. In CCM mode, the input current waveform can be defined according to the converter input voltage and the output power requirement. For the CCM operation mode deriving the inductor current is a straight forward calculation [7], but for the BCM mode, the switching frequency varies across the line cycle.…”

Abstract-This paper presents an analysis and comparison of boundary conduction mode (BCM) and continuous conduction mode (CCM) in single phase power factor correction (PFC) applications. The comparison is based on double pulse tester (DPT) characterization results of state-of-the-art superjunction devices in the 600V range. The measured switching energy is used to evaluate the devices performance in a conventional PFC. This data is used together with a mathematical model for prediction of the conducted electromagnetic interference (EMI). This allows comparing the different devices in BCM and CCM operation modes and evaluating the performance as a function of the PFC power density and efficiency.
