A new ZC-ZVS forward converter
Proceedings of Applied Power Electronics Conference. APEC '96, 2002This paper presents a steady-state analysis with complete characterization of ZCS-ZVS forward power converter operation. The nondissipative snubber associated with a forward power converter provides the soft commutation switching. The proposed approach allows building a converter with high frequency operation.

Simulation of PWM Forward Converter
1997By this time, it is fair to say that any scientific topic, be it technical or social, can be simulated, or modeled, with a computer; provided the necessary mathematical equations are available and absolute accuracy is not unreasonably expected.

Buck-boost integrated forward converter
2005 European Conference on Power Electronics and Applications, 2005An integrated converter is a synthesized converter based on the overall system integration, which is simplified by the system objective and can implement the system functions similar to the discrete converters. An integrated converter consists of converter sets; each converter set has a special function defined by the designer.

Implementation of an interleaved ZVS forward converter
2009 International Conference on Power Electronics and Drive Systems (PEDS), 2009A parallel zero voltage switching (ZVS) forward converter with half-bridge topology is presented in this paper. Two converter modules are connected in parallel in the output side to share the load current. In the primary side, two converter modules use the same power switches so that the semiconductor devices are reduced in the proposed converter ...

Forwarding Control of a Boost Power Converter
IFAC Proceedings Volumes, 2001Abstract We consider in this paper the asymptotic stabilization of a Boost power converter. The feedback control law is synthesized by using the systematic Forwarding procedure, which allows one to achieve the control design by considering the Boost controlled system as the interconnection of two basic electric circuits. A nonlinear transformation is

A self-resonant PWM forward converter
Proceedings of IECON'94 - 20th Annual Conference of IEEE Industrial Electronics, 2002This paper presents a new forward power converter which operates without commutation losses. This approach is based on the principle of self-resonance, i.e. an auxiliary voltage source output feeds the resonant circuit charging a capacitor which provides the condition for the zero voltage switching (ZVS) of the main switch.

A built-in-input filter forward converter
Proceedings of 1994 Power Electronics Specialist Conference - PESC'94, 2002Employing the transformer leakage inductance and two cross-coupled capacitors, a built-in input filter forward converter (BIFFC) configuration is proposed to shape the input current waveform to a nonpulsating fashion. Consequently the ripple and harmonic component of the input current can be significantly reduced without adding a large input filter. In

Sliding mode controlled forward converter
2015 IEEE 9th International Conference on Intelligent Systems and Control (ISCO), 2015The control methods for DC-DC converters should consider wide input voltage ranges and load variations to guarantee stability under wide operating conditions. The switching action of DC-DC converters makes them variable structure systems. Sliding Mode controller is a robust nonlinear controller that can be used for such variable structure systems.

A dual mode forward/flyback converter
1982 IEEE Power Electronics Specialists conference, 1982This paper presents a single transistor dc-dc converter that combines both forward and flyback action. The resulting circuit is ohmically isolated and can operate over a wide range of input-to-output voltage ratios. An analysis of the circuit indicates that the forward and flyback portions of the circuit interact to produce three distinct regions of ...

On lessening the cross regulation in a forward converter
The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004A new method is proposed in this paper to improve the cross regulation in a multioutput forward converter. An objective function is determined for each of the multiple DC outputs to track its reference. The error of each output is maintained within an acceptable level.
