Conclusion A new hybrid control method can combine a conventional PWM operation and a quasi-resonant operation. The proposed approach reduces the switching loss and improves efficiency at medium- and light-load condition without increasing the conduction loss. The proposed scheme was verified through experimental 90~265 VAC/5 V, 30 W off-line flyback converters. < AD05062Therm 4/7/06 2:11 PM Page 1 For more information, enter.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 301 ·8 &10 Amp Switching · Dielectric strength 3000/4000 Vrms ·Single and dual coil latching versions available ·Epoxy sealed version available LATCHING & HIGH INRUSH RELAYS AZ880/881 ·16 Amp switching ·High inrush version available (80 A) ·Dielectric strength 5000 Vrms ·Class B (130°C) standard ·Class F (155°C) versions available ·Low cost Also available our Miniature High Power Relays AZ762F & AZ762H.
