Finally, a 690 W prototype is implemented to experimentally examine and investigate the proposed converter. To analyze the topology, the continuous conduction mode of operation, voltage, and current stress of the devices, as well as an efficiency analysis are discussed. Hence, the operation and control are simple. The duty cycle and the switching pulses for the two switches are identical. In addition, by simply varying the duty ratio of the two switches, a wide output voltage range is possible. Since the topology does not consist of a coupled inductor or transformer structure, voltage spikes during the turnoff process are eliminated. When compared to conventional converters, the proposed converter achieves a high step-up gain with reduced switch stress. The topology is derived from the Cuk converter by using two switches, three inductors, a voltage-lift capacitor, and switched-capacitors. In this paper, a new topology based on the Cuk converter is proposed to meet the high step-up gain, reduced switch stress, and continuous input current requirements. High voltage conversion with a continuous input and output current is the prime requirement for electric vehicles and renewable energy applications.
