A novel topology of isolated input-series and output-series (ISOS) full-bridge bidirectional DC/DC converter is described in this paper for the application requirement of high input voltage and high output voltage, which can be used in the next generation medium and high voltage power conversion systems. The proposed novel isolated bidirectional DC/DC converter not only can apparently decrease the stress of the switches, but also have the advantages, such as galvanic isolation, ease of realizing soft-switching control, high power density, and so on. In this paper, working principle of the proposed DC/DC converter is discussed in detail, the corresponding equations are derived, and the soft switching implementation is discussed too. In the end, simulation is done through PSIM to certify the feasibility of the proposed DC/DC converter and accuracy of the criterion.

A high voltage gain modified SEPIC converter is proposed in this paper. This proposed converter has many advantages i.e., high output voltage, lower voltage stress, high efficiency, voltage gain is high without any coupled inductor and transformer, continuous input current. Thus, there is no overshoot voltage at turn-off process for switches. By using single switches, the CCM mode operation can be easily controlled by this converter, so control system is simple and also wide output values is obtained only by modifying the duty cycle. This modified converter has lower components than conventional converter. The operating modes and design of modified converter are discussed. The output power of this converter is 6 watts. By this converter, this converter capable of developing the two and half times of input voltage. The PV system also used this converter to develop high voltage gain. This high voltage gain is achieved by using MATLAB/SIMULIMK platform.

Along with the development of technology about audio soundsystems, innovations and new designs about audio are very many, music is an entertainment that is almost every day encountered by people today, Amplifier products that are commonly marketed (finished products) are still very dominated by the outside market country. GB Power Amplifier class (Ground Bridge) is one type of power amplifier that requires a high input voltage in the audio world, the use of a combination of suitable transformers and with the output voltage transformer that is able to meet the required power capacity for the amplifier without having to search for transformer with a high output specification. So a good component selection can make the power amplifier's performance to the maximum.

Circulating Current

A hybrid PWM converter is proposed and investigated to realize the benefits of wide zero-voltage switching (ZVS) operation, wide voltage input operation, and low circulating current for direct current (DC) wind power conversion and solar PV power conversion applications. Compared to the drawbacks of high freewheeling current and hard switching operation of active devices at the lagging-leg of conventional full bridge PWM converter, a three-leg PWM converter is studied to have wide input-voltage operation (120–600 V). For low input-voltage condition (120–270 V), two-leg full bridge converter with lower transformer turns ratio is activated to control load voltage. For high input-voltage case (270–600 V), PWM converter with higher transformer turns ratio is operated to regulate load voltage. The LLC resonant converter is connecting to the lagging-leg switches in order to achieve wide load range of soft switching turn-on operation. The high conduction losses at the freewheeling state on conventional full bridge converter are overcome by connecting the output voltage of resonant converter to the output rectified terminal of full bridge converter. Hence, a 5:1 (600–120 V) hybrid converter is realized to have less circulating current loss, wide input-voltage operation and wide soft switching characteristics. An 800 W prototype is set up and tested to validate the converter effectiveness.
