This paper proposes a new non-isolated dual-input zero-voltage switching (ZVS) dc-dc boost converter with medium voltage gain. Two input ports of the are current-fed and suitable for unidirectional dc power source, chargeable energy storage. The proposed basic circuit composed three cascaded switches, which at their connection points join to inductors switched capacitor multiplier (VM) cell is accompanied. Using this VM gain achieves two times that in conventional also half stress across switches. Through powers from source (like PV) battery can be accepted. Taking triangular resonant current frequency, third inductor aids reach ZVS switches turn-on diodes stop conducting ZCS all operation conditions. As result, low losses, reduced reverse recovery issue, high efficiency accessible especially higher output powers. PWM manner individual duty ratios, allowing regulate control extracted port. has been analyzed detail find its different operating modes, determine currents, estimate losses components design system. Behavior system examined by low-power laboratory prototype tested under four practical benefits simple compact structure, ports, number magnetic elements, efficiency.

This study develops three new machine learning-based algorithms using the SVR prediction approach. The overall objective is to enhance performance of PV shunt active power filter (PV-SAPF) in order successfully fulfil its multi-functionality terms generation along with quality upgrades. first technique, named "SVR-INC MPPT", incorporates an ML-based duty cycle function, which intended speed up MPP finding process. algorithm then switches INC approach, guaranteeing accurate steady-state response. second and third techniques are Adaline for DC voltage regulation, SRF strategy reference currents generation. adopted approaches based on two weights performing actions proportional integral controller, nine fundamental currant extraction. advantage lies overcoming Adaline-based algorithm's limitations, requiring on-line large number iterations. Three simulation scenarios six controllers classical intelligent techniques, prove effectiveness proposed ML-controllers. results display (i) immediate harmonics identification (minimizing extraction error by 99% compared approach). (ii) a response time reduction range from 65% 100%, output controller PI-based one. (iii) THD 2.41% 4.45%. (iv) 20ms 0% overshoot, respectively (v) overshoot 0.04% 1.1%. Consequently, these offer best options powerful PV-SAPF system tracking harmonic attenuation. Moreover, obtained metrics comply IEEE-519 standard.
