We investigate Learning Classifier Systems for online environments that consist of real-valued states and which require every action made by the agent to count towards its performance. Two Learning Classifier System architectures are considered, ZCS and XCS. We use an interval representation with these Learning Classifier Systems for the rule conditions together with roulette wheel action selec...

This paper presents a new soft switching flyback-forward PWM converter. The proposed circuit employs an auxiliary circuit to achieve soft switching condition for switches and also absorbs the voltage spikes caused by the leakage inductance of transformers in the converter. In the proposed converter main switch operates at ZVS and the auxiliary switch operates at ZCS. The proposed converter has ...

In this paper, based on the switching cell approach, a unified steady state analysis for families of soft-switching dc–dc converters with complete unified design equations will be presented. The concept of the unified approach and step by step procedure for a generalized process are discussed and applied to selected soft-switching families such as zero-voltage-switching (ZVS) and zero-current-s...

This paper is dealt with the examination of possibilities of the algorithm of autonomous agent navigation. The ANIMAT problem was proposed to study the possibilities of ZCS classifier system learning. A ZCS classifier system is purely reactive. For this system it is essential to have a possibility to identify the global state of the environment by the input message. This shortens the applicatio...

An improved active snubber cell is proposed for ZVT-ZCT PWM DC-DC boost converter. Zero voltage transition (ZVT) turn on and zero current transition (ZCT) turn off is provided by this active snubber cell. There is no extra current or voltage stresses on the main switch. Also, zero current switching (ZCS) turn on ZCT turn off is provided for the auxiliary switch. Although there is no extra volta...

A new resonant switch and a new family of zerocurrent and zero-voltage mixed-mode switching quasi-resonant converters (QRC’s) called single-cycle resonant converters (SCRC’s) are proposed to improve the performance of the conventional QRC’s. The proposed SCRC’s, which include two active switches operated with zero-current switching (ZCS) and zero-voltage switching (ZVS), respectively, show very...

The multi-phase implementation in the QR (quasi resonant) ZCS (zero current switching) SC (switched capacitor) bidirectional DC-DC converter structure has been proposed to reduce current ripple, switching loss and significantly increase the converter efficiency and power density. This approach provides a more precise output voltage to obtain voltage conversion ratios from the double-mode versus...

A novel interleaved boost and buck converter with zero-voltage switching (ZVS) and zero-current switching (ZCS) characteristic is proposed in this paper. By using the interleaved approach, this topology not only decreases the current stress of the main circuit device but also reduces the ripple of the input current and output voltage. Moreover, by establishing the common soft-switching module, ...
