Berkembang pesatnya pemanfaatan energi terbarukan salah satunya untuk sinar matahari dengan menggunakan panel surya, dimana surya berfungsi mengubah ke listrik. Sinar dapat diperoleh secara gratis serta ramah lingkungan. Terdapat banyak kelebihan dari melalui namun terdapat kekurangan adalah menghasilkan listrik yang berfluktuasi tergantung iradiasi sehingga tegangan keluaran tidak konstan. Unt...

Design and application of led driver with isolated cuk converter for 10W is realized in this paper especially automotive purposes. The advantage topology than conventional Cuk to have electrical isolation supply load providing same polarity output. Besides, power model including constant voltage exponential models obtained employed simulation study comparison. Furthermore, maximum current limit...

The main objective of this research work is to implement and compare four control methods, i.e., PWM with periodic carrier, Zero voltage switching, Zero Current switching, chaotic PWM with chaotic carrier in terms of their performance in suppressing ripples, reducing peaky electromagnetic inference and increasing converter conversion efficiency in MPPT circuits of the solar PV powered Cuk conve...

This paper proposes a new hybrid flyback-Cuk (HFC) converter. The converter consists of single switch, isolated input, and dual output based on flyback Cuk topologies. HFC topology is proposed to reduce switching losses improve the duty cycle range over which voltage can be stepped down, would ultimately lead an increase in efficiency. For step-down capability, traditional topologies (flyback o...

A new combined boost-Cuk-forward (CBCF) converter with ripple-free input current and low switch voltage stress is proposed for high step-up applications. Two coupled inductors are applied to achieve as well balanced dc-link voltages, wherein the former placed in series boost diode, latter formed a forward converter. Because these output Cuk inductor, also attained. The run at discontinuous cond...
