Buck-flyback DC-DC converter

IEEE Transactions on Aerospace and Electronic Systems, 1988
It is difficult to obtain a large input/output voltage ratio with a DC-DC converter, because the duty factor d may not reach very small values. For the same reason, it is difficult to obtain an output voltage that is adjustable in a large range. A DC-DC converter circuit is proposed that overcomes this limitation by performing a voltage ratio d/sup 2//(

IncCond MPPT control using flyback converter

2013 International Conference on Electrical Machines and Systems (ICEMS), 2013
MPPT is widely used in the application of photovoltaic system. This paper shows the circuit which improves efficiency of photovoltaic system using soft switching flyback and decreases a loss in elements at switching to control the IncCond, one of the MPPT.

Radio frequency dc-dc flyback converter

Proceedings of the 43rd IEEE Midwest Symposium on Circuits and Systems (Cat.No.CH37144), 2002
An RF (radio frequency) dc-dc converter has been developed to demonstrate the possibility of using a flyback configuration at 63 MHz. The converter consists of two sections: a variable pulse width generator (PWG) and a FET switch with a transformer and a detector.

Diode-less multiple output flyback converters

APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition, 2002
A secondary post PWM regulator ASIC is proposed for multiple-output flyback converters. The ASIC controls two external MOSFETs to achieve a diode-free secondary for high efficiency, while providing accurate PWM regulated output voltages.

Cross regulation in flyback converters: solutions

IECON'99. Conference Proceedings. 25th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.99CH37029), 2003
Studies at UCI have shown that cross regulation in multiple output flyback converters can be significantly improved when the clamp voltage is lowered to slightly above the reflected output voltage. In this paper, three solutions for reducing the clamp voltage are investigated.

A 400 W flyback converter

Conference Proceedings., Eleventh International Telecommunications Energy Conference, 2003
It is demonstrated that it is possible to manufacture a very compact high-power switch-mode power supply based on the flyback technique using standard components, with no sacrifice in performance and operation at 80 kHz. A superior flyback converter can be designed on the basis of the following criteria: (1) choosing a pulse ratio to optimize the ...

Flyback Converter Output Voltage Stabilization

IEEE Transactions on Aerospace and Electronic Systems, 1987
The expression of the flyback converter output voltage (output power) is derived as a function of the supply voltage, load resistance, transformer ratios, transistor current gain, and base-circuit resistor value. Switching period and duty cycle are also calculated. A converter circuit is designed having stabilized output voltage, with respect to supply
