“…The input voltage source is directly attached to the X converter and input of Y converter is a series connection of input voltage source and output voltage of X converter. The total output voltage of the XY converter family is equal to the inverting sum of output voltage of X converter and Y converter as in (1).…”

“…This is because the energy sources required for the massive power generation are exhaustible. On the other hand, renewable energy sources are reliable and plentiful and can be locally produced and therefore are not vulnerable to any kind of risks [1]- [4]. Hence energy management focus on the widespread use of renewable energy resources for power generation.…”

Abstract-A New breed of a buck boost converter, named as the XY converter family is proposed in this article. In the XY family, 16 topologies are presented which are highly suitable for renewable energy applications which require a high ratio of DC-DC converter; such as a photovoltaic multilevel inverter system, high voltage automotive applications and industrial drives. Compared to the traditional boost converter and existing recent converters, the proposed XY converter family has the ability to provide a higher output voltage by using less number of power devices and reactive components. Other distinct features of the XY converter family are i) Single control switch ii) Provide negative output voltage iii) Non-isolated topologies iv) High conversion ratio without making the use of high duty cycle and v) modular structure. XY family is compared with the recent high step-up converters and the detailed description of XY converter family and its topologies are presented. The simulation results are provided and it confirms the feasibility, functionality and validity of the concepts of the proposed XY converter family.

Abstract. The assurance of the electromagnetic compatibility of sensitive smart metering systems and power electronic converters, which introduce high-level electromagnetic interference is important factor conditioning reliable operation of up to date power systems. Presented experimental results have shown that currently binding, frequency domain tests are ineffective for the evaluation of data transmission error hazards. The proposed in this paper mathematical, time-domain model, based on Diophantine equation, enables evaluation of data transmission errors caused by interference introduced by DC-DC power electronic interfaces with deterministic modulation. In the paper there have been presented possible application areas for the proposed model. Thus, evaluation of the probability of the appearance of data transmission errors, caused by interference generated by power electronic converters, is important for both cognitive and technical reasons. Elaboration of the presented mathematical model has enabled explanation of significant differences in experimentally obtained distributions of awaiting times for data transmission errors caused by interference generated by a DC-DC converter with random [9-11] and deterministic modulation. The evaluated probability of the appearance of data transmission error may become a useful factor supporting the development of data transmission systems.The DC-DC converter was selected as an interference source for mathematical analyses of data transmission errors caused by interference generated by converters with deterministic modulation. A detailed description of the interference introduced by a DC-DC converter [12][13][14] has been presented in our previous paper [15]. Deterministic vs. random modulation of power electronic interfacesRandom modulation of power electronic interfaces is often recommended as an EMI reduction technique [16,17]. In fact the utilization of random modulation does provide ostensible reduction [18,19] of the interference levels measured, in accordance with EMC standards, in the frequency domain. Fig. 1 shows the experimental results for conducted emission generated by a DC-DC converter with deterministic and random modulation, measured using average detector, in accordance with the EN 55022 standard, with the upper limit of the frequency range reduced from 30 MHz to 5 MHz for better clarity of the results.
