This paper presents the design considerations and analysis for an interleaved boundary conduction mode power factor correction buck converter. A thorough analysis of the harmonic content of the AC line current is presented to examine the allowable voltage gain (K value) for meeting the EN61000-3-2, Class D standard while maximizing efficiency. The results of the harmonic analysis are used to derive the required value of K and therefore the output voltage necessary to meet the class D requirements for a given AC line voltage. The discussed design consideration and harmonic current analysis are verified on a 300W universal line experimental prototype converter with an 80V output. The measured efficiencies remain above 96% down to 20% of the full load. The input current harmonics also meet the IEC61000-3-2 (class D) standard.

“…In general, interleaving techniques can be classified into two categories: the open loop master-slave method ( [11]- [12]) and the PLL based closed loop method ( [13]- [17]). The open loop master-slave method has difficulty in guaranteeing stable BCM operation against tolerance of the inductor values and PWM control circuits.…”

“…In high power applications, continuous conduction mode (CCM) PFC is used to reduce the ripple currents and the conduction losses. However, in low-tomid power applications, critical conduction mode (CRM) boost PFC is widely used although it has a large ripple current, because of its low switching losses and simple constant on-time control [1]- [13].…”

In many low-to-mid power applications, critical mode boost power factor corrector converters are widely used because of its low switching loss and simple control. However, near the zero crossing of the input line voltage, an input current distortion and a low power factor are caused by delayed switching period and negative input currents. Generally, an additional on-time method according to the input voltage is used to compensate the input current distortion. However, a detailed quantitative analysis for the exact additional on time has not been studied till now. In this paper, the explicit form of the optimized additional on time has been obtained using a quantitative analysis and the advantage of the digital control. From a state trajectory and "net input charge" analysis, it is shown that the optimized on time should be related to not only the input voltage, but also the output power. Also, in order to improve the efficiency in a high input and light load condition, circulating currents are reduced in the inevitable dead angle with a gate turning-off technique. By using digital control, the optimized additional on time and the gate turn-off technique have been implemented with the 90-230 V rm s input and 380 V/200 W output prototype.Index Terms-Additional on time, critical mode (CRM) boost power factor corrector (PFC), digital control.
