6 SARS, Diode for Snubber Circuit Using FLR Diode Using SARS VAC Snubber VAC Snubber Discharge Loop Discharge Loop Serge Absorb Loop SARS Serge Absorb Loop Power Supply Control IC Power Supply Control IC Controller V DS Controller V DS When MOSFET turns off, serge current flows on Surge Absorb loop and It is absorbed by capacitor. The electrical charge of capacitor is discharged through Discharge loop. The power is not transferred to the secondary side. Thus it becomes power dissipation. When this capacitor is discharged, the recovery current of the diode flows on the MOSFET. FLR (Fast Recovery Diode) is beneficial for preventing the MOSFET damage. When SARS is used, the electrical charge of the capacitor is discharged through Discharge loop in recovery period of SARS and this power is transferred to the secondary side. Thus high circuit efficiency can be achieved. When this capacitor is discharged, the instantaneous recovery current of the diode flows on the MOSFET. It is recommended to add a resistor in series with SARS for the damage control of MOSFET. (Patented circuit) P.6

16 Points of Selection for Bypass Diode 1. Functions of Bypass Diode For Protecting MOSFET and Rectification Diode from Inrush Current When the inductance is saturated by the inrush current, large current flows to the rectification diode, the diode has a risk of breakdown. Since saturation of inductance is prevented by flowing inrush current to the bypass diode, MOSFET and rectification diode are protected. For protecting Bridge Diode from Lightning Surge If the lightning surge is injected to the circuit, bridge diode has a risk of breakdown. Thus, the bypass diode changes the energy of the lightning surge flow and it is absorbed by electrolytic capacitor. 2. Electrical Characteristics of Bypass Diode VAC PFC Control IC Bypass Diode Rectification Diode In order to change flow of the inrush current and the lightning surge to the bypass diode, VF of Bypass diode needs to be lower than VF of rectification diode. When output voltage becomes higher than input voltage, the bypass diode turns off. Thus recovery characteristic of the diode is not considered. The pulse current and VF characteristic needs to be considered for the diode selection. V PFCOUT GND Key points of Bypass Diode selection; 1) Acceptable large current in short period (I FSM > 50A) 2) Low VF than rectification diode ( 0.95V) P.16

17 Point of Selection for Rectification Diode The Rectification Diode of PFC should be selected according to the operation mode of PFC Features Advantages Disadvanta ges Discontinuous Conduction Mode (DCM) There is a period when the current that runs through L becomes zero (Frequency is fixed) Critical Conduction Mode (CRM) The current that runs through L becomes zero for an instant (ON time is fixed) L value: Medium L value: Large L value: Small I L I L I L MOSFET turns ON when the current that runs through a diode becomes zero There is almost no recovery current in the rectifier diode Switching noise is small With almost no recovery current, better efficiency is achieved when focusing on VF Peak current of MOSFET is large Ripple of input current is large Normal mode noise is large Key points in selecting a rectifier diode ; DCM, CRM: Low VF Diode ( 1.3V) CCM: Fast Recovery Diode (trr 50 ns) with Low VF Continuous Conduction Mode (CCM) The current that runs through L does not become zero (Frequency is fixed) Peak current of MOSFET is small Ripple of input current is small Normal mode noise is small MOSFET turns ON when the current runs through the diode Recovery current runs through the rectifier diode, resulting in large loss Switching noise is large To reduce loss, use a diode with excellent reverse recovery time (trr) P.17
