This paper presents a space vector modulation strategy for three-phase indirect matrix converter to reduce the common-mode voltage and maintain output performance. To peak value of 57.7% input phase voltage, three active vectors are used generate desired with arbitrary amplitude frequency, instead using both zero as in traditional strategy. Although is reduced, waveform quality deteriorates due...

Electrochemical energy storage system play an important role in the reform of national and construction Internet. Whether small or large capacity battery converters, characteristics their power electronics can generate high frequency common mode voltage that be potentially harmful to system. This paper systematically investigates common-mode interference (CMI) electrochemical The mechanism is r...

This paper presents some aspects of building reprogrammable system using current mode gates. With this approach it is possible to extend system on a chip solutions into the area of mixed mode applications. CMOS current mode gates consume almost constant current from the power supply and therefore are suitable for mixed mode operations. Contrary to voltage mode digital gates, presented in the pa...

The use of the average-current-mode control in the recently introduced two-input buck postregulator is studied in this paper. Using this type of control, the attenuation of the input voltage ripple (100–120 Hz) increases in relation to the one obtained when a conventional voltage-mode control (with or without feedforward) is used and, therefore, lower bulk capacitors can be used to obtain a ver...

A new fully differential (FD) low input impedance CMOS current buffer with low voltage, and low power operation is presented. The low input impedance is achieved by remarkable reduction of the input node voltage swing using a novel double feedback scheme. Some advantages of the proposed double feedback scheme over the conventional (either positive or negative) feedback techniques are: lower inp...

In this paper, a new structure of step-up dc-dc converter by using coupled inductor and active-clamped circuit is proposed. The proposed converter generates high voltage gain in comparison with the conventional dc-dc converters. Duo to using active-clamped circuit in the proposed topology the voltage stress on main switch is reduced. In addition the zero voltage switching (ZVS) in ON-state of m...

A new single-phase transformerless grid-connected PV inverter is presented in this paper. Investigations in transformerless grid-connected PV inverters indicate the existence of the leakage current is directly related to the variable common-mode voltage (CMV), which is presented in detail. On the other hand, in recent years it has become mandatory for the transformerless grid-connected PV inver...
