“…Hence, the values of the inductor and capacitor of the output L-C filter can be reduced, thereby reducing the converter size. This means that it is possible to control a wide range of output voltages and satisfy the current ripple rates required by various batteries with different electrical characteristics [21][22][23][24][25][26][27][28]. conditions as a multilevel converter.…”

Considerable efforts are being made to reduce CO2 emissions and thereby solve the problems of environmental pollution and global warming. Technologies for environmentally friendly transportation are being developed using batteries. In particular, with the increase in urbanization and one-person households, e-mobility products are drawing increasing attention as short-distance transportation devices. Among these vehicles, personal mobility devices (PMDs) are receiving attention as new transportation devices that are simple to operate. This paper proposes a new multilevel charging system that is advantageous in responding to the charging voltage specifications of various mobile devices with a single charging system while ensuring a low charging current ripple. The proposed diode-parallel multilevel converter consists of an independent Buck converter in series. The switch of the buck converter is configured at the negative terminal of the input power source so that the gate amplifier voltage is used as the power supply voltage; it can therefore be simply configured without a separate gate amplifier power supply. In addition, it is improved so as to have a wider charging voltage range in a low output voltage region and a better efficiency than the existing diode series multilevel converter. To verify the feasibility of the proposed system, simulations were performed using the software PowerSIM(PSIM), and, in order to verify the validity, a prototype charging system was fabricated to compare and analyze losses according to operating conditions.

“…Several high-voltage gain DC-DC step-up converters for renewable energy applications can be found in the literature [26][27][28][29][30][31][32]. In this section, the proposed converter is compared only to the converters that have shared ground between the input and the output, and do not have any floating active switch or coupled inductors.…”

This paper presents a non-isolated DC–DC boost topology with a high-voltage-gain ratio for renewable energy applications. The presented converter is suitable for converting the voltage from low-voltage sources, such as photovoltaic panels, to higher voltage levels. The proposed converter consists of a multiphase boost stage with an interleaving switching technique and a voltage multiplier cell to provide a voltage level at a reduced duty cycle. The interleaved boost stage consists of two legs and can be either fed from single or multiple voltage sources with the ability to control each source separately. The voltage multiplier cell can increase the voltage level by charging and discharging the capacitors. Several advantages are associated with the converter, such as reduced voltage stress on semiconductor elements and a scalable structure, where the number of voltage multiplier cells can be increased. The inductors in the interleaved boost stage share the input current equally, which reduces the conduction loss in the inductors. The input and the output of the converter share the same ground, and all active switches are low-side, which means no feedback or signal isolation is required. The theory of operation and steady-state analysis of the converter operating in the continuous conduction mode is presented. Components selections and efficiency analysis are presented and validated by comparative analysis and simulation results. A 0.195 kW experimental prototype was designed and implemented to convert the voltage from 20 V input source to 400 V output load, at 50 kHz. The test results show a high-performance of the converter as the maximum efficiency point is above 97%.
