The Time Domain

The resonant converters have attracted a lot of attention because of their high efficiency and low switching losses. This paper presents the analysis of a high voltage gain non-isolated step-up DC-DC converter topology using resonant technology. The proposed converter configuration has reduced number of power semiconductor switches compared to the existing isolated converter topology having four semiconductor switches. The proposed topology employs capacitor-inductor-capacitor (C-L-C) resonant circuit configuration. The size of the proposed converter and the losses in the converter are greatly reduced. Both the converters with resonant components are simulated in Matlab/Simulink platform to validate their performance. The time-domain simulation results demonstrate that the proposed non-isolated converter gives improved voltage gain compared to the existing two-stage isolated resonant DC-DC converter.

In this paper, a three-layer GaAs photoconductive semiconductor switch (GaAs PCSS) is designed to withstand high voltage from 20 to 35 kV. The maximum avalanche gain and minimum on-state resistance of GaAs PCSS are 1385 and 0.58 Ω, respectively, which are the highest values reported to date. Finally, the influence of the bias voltage on the avalanche stability is analyzed. The stability of the GaAs PCSS is evaluated and calculated. The results show that the jitter values at the bias voltages of 30 kV and 35 kV are 164.3 ps and 106.9 ps, respectively. This work provides guidance for the design of semiconductor switches with high voltage and high gain.

Interleaved Structure

High step-up dc-dc converter is an essential part in several renewable energy systems. In this paper, a new topology of step-up dc-dc converter based on interleaved structure is proposed. The proposed converter uses three energy storing capacitors to achieve a high voltage gain. Besides the high voltage gain feature, the proposed converter also reduces the voltage stress across the semiconductor switches. This helps in using low rating switching devices which can reduce the overall size and cost of the converter. The operating principle of the proposed converter is discussed in detail and its principle waveforms are analyzed. An experiment is carried out on a 20 V input, 130 V output, and 21 W power prototype of the proposed converter in the laboratory to verify the performance of the proposed converter. An efficiency of 91.3% is achieved at the rated load.
