In recent years, the design of new electronic equipment requires the development of new topologies for power supplies. The above is clear for portable equipment, which many times is classified as light loads. These new applications require power supplies with wide conversion ratios and better efficiencies. A solution to this problem is the use of two or more conventional converters connected in cascade, which have been proposed to operate in continuous conduction mode; however, if these converters operate in discontinuous conduction mode (DCM) a better efficiency is achieved. In this paper, a cascade connection based on two boost converters operating in DCM is proposed. A step‐by‐step procedure for the proper design of the cascade connection is given. Simulation and experimental results for a low power converter validate the proposed methodology. Thus, the design procedure will help in designing converters for light power applications. © 2020 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

“…In high power applications, CCM is more suitable compared to the DCM due to low input current ripple and low conduction losses. Besides, CCM generates non-pulsate current and the value of input current is not less than or equal to the zero values [22,23]. Thus, the lifetime of the converter can greatly be improved.…”

<p>The continuously increasing demand for control on electric power equipment has led to the rapid technological development in various applications such as renewable energy, electric drives, and communication. Pulse Width Modulation (PWM) switching is an important technique to control the output voltage. PWM signals can either be generated using digital controller or analog controller. Digital controllers are widely used to generate PWM signals due to their reliability in solving complex algorithms within short amount of time. Multiphase boost converter is capable to overcome high input current ripple, current stress and semiconductor losses in conventional boost converter. This paper proposes a PWM switching scheme for multiphase interleaved converter using Field Programmable Gate Array (FPGA). The proposed switching scheme uses PWM switching technique that is implemented by programming Altera DE2-70 board. The duty cycle can be easily adjusted using assigned switches on the Altera board. For validation, switching frequency was set to 100 kHz, and then switching signal was observed using oscilloscope.</p>

“…Large number of inductors, capacitors, and control switches with various current and voltage rating, high voltage stress across switch, and complex control circuitry are the main drawback of cascaded converter. Quadratic converter is proposed by cascading two boost converters in special manner using single switch to overcome the drawback of large number of control switches in cascaded converter [9]. The high voltage stress across switch (equal to output voltage) and large rating of inductor and capacitor are the main drawback of quadratic converter.…”

In this article, an improved Multistage Switched Inductor (M-SI) based power converter or Improved Multistage Switched Inductor Boost Converter (Improved M-SIBC) is proposed for renewable applications which provides a key to enhance voltage conversion ratio. In last decades, Switched Inductor (SI) and M-SI are the popular network/technique employed in DC-DC converter to achieve high voltage conversion ratio. An improved SI and M-SI network/technique is proposed to enhance the existing the voltage conversion capabilities of SI and M-SI by replacing central uncontrolled switches by polarized capacitor. The anticipated power converter configuration combines the feature of conventional boost converter and improved M-SI. The voltage conversion a capability is depends on the number of stages of M-SI and ON time of control switch. The operation modes and characteristics of proposed converter with steady state mathematical analysis for N-stages are discussed in detail. Moreover, the proposed converter compared with existing converter in terms of voltage conversion ratio and the detail of number of components is also provided. Matrix Laboratory R2016a simulation results of 100W proposed improved M-SIBC with considering three stages are provided and the results always shows a good agreement with theoretical analysis and also validates the improved M-SI network concept.
