In this paper, a bidirectional full-bridge phase-shift converter with high transformation ratio scheme is proposed. The main architecture of dual active circuit. By using modulation, the energy can be transmitted between high-voltage-side and low-voltage-side, also make power switches have function soft-switching. This designed transmission 1kW digital signal processor TMS320F28335 utilized as ...

Abstract A fully soft switched high step‐up/down bidirectional converter is presented in this paper. The voltage conversion ratio achieved by a pair of coupled inductors along with capacitor while all active switches operate at zero switching. To provide switching condition for the main and absorb leakage inductance energy inductors, clamp circuits are utilized both operating modes. Furthermore...

This paper shows a three-phase series resonant DC-DC boost converter simulation model with double LLC tanks (SRC-W-DLLC-RTs) for hybrid solar wind system (HSWS) battery energy storage DC load. An intrinsic drawback of solar-wind technology is its intermittent and weather-dependent output voltage. MPPT control algorithm-based converter, which offers interfaces between load, can overcome this iss...

During the last two decades, it has been seen that power conversion from one form to another of energy was a serious issue in electronics. After production converters such as rectifiers convert AC-DC, inverters DC-AC, voltage regulators, choppers, and cycloconverters make possible conversion. In 1980, Venturini presented concept Matrix Converter electronics; consists bidirectional IGBT switches...

background: we sought to assess right ventricular (rv) systolic and diastolic functions via tissue doppler imaging (tdi) in order to discriminate right-to-left (bidirectional) from left-to-right intracardiac shunts. methods: a tissue doppler velocity study via doppler echocardiography was performed in 20 patients with left-to-right shunt (without evidence of significant pulmonary hypertension) ...

The conventional AC/AC matrix converter uses 9 bidirectional switches. The 3×3 switches give 512 combinations of switching states, which are decreased to only 27 feasible states, if the two basic rules (preventing the short-circuit and open-circuit) to operate the converters safely are applied. The output voltage of a basic matrix converter is limited to 866 . 0 2 3 ≈ of the input voltage. In t...
