“…Working of SMPS : SMPS operate using high frequency switches, these switches can be MOSFET/IGBT. Basic requirement of high frequency is to reduce the transformer core area and further to increase the overall efficiency (8) . Other advantages of use of SMPS are such as control over circuits result in fast control in charger and can avoid the failure of charger, by using of micro-controller, system become flexible for operation and no major changes to be done in circuity for modification.…”

Objectives: The study's primary goal is to investigate a Switch Mode Power Supply (SMPS)-based battery charger for electric vehicles (EV) and compare the use of various charging techniques. Methods: This study provides ideas for the requirements of an SMPS-based battery charger; design and development of the charger; and operation of the charger with different charging techniques. Further, the development of the proposed charger, its testing and performance examination are carried out. This study also gives details about circuit components; circuit selection criteria of an SMPS-based battery charger; charging methods; and technical specifications of the charger. Verification and testing of the proposed charger is also done with the help of a 24 V battery. Findings: It is found that the proposed battery charger can be more advantageous than conventional battery chargers in a variety of ways, including improved efficiency (nearly 88%), light weight, better protection (reverse battery connection, short circuit, overload), and reliable operation (no need to monitor, automatic cut off, and so on). Novelty: Work was done for the development of an SMPS-based battery charger to eliminate existing issues as mentioned in the findings with traditional charger systems. The proposed charger helps to eliminate the sulfation effect on lead acid batteries to improve battery life (50-100 cycles). It helps to not only promote the "Made in India" scheme but also mass adoption of electric vehicles.

“…In order to study the power supply for electronic devices, researchers have made great efforts in transformer design [12][13][14][15] and circuit design including the circuit topology towards flyback converter and forward converter [16][17][18][19][20][21][22][23][24][25][26]. As one of the most important modules of DC-DC or AC-DC conversion, almost all the commercial transformers are fabricated by metal wire winding that suffers large size and non-batch fabrication.…”

A silicon-chip-based 3D metal solenoidal transformer is proposed and developed to achieve AC-DC conversion for integrated power supply applications. With wafer-level micro electromechanical systems (MEMS) fabrication technique to form the metal casting mold and the following micro-casting technique to rapidly (within 6 minutes) fill molten ZnAl alloy into the pre-micromachined silicon mold, 45-turns primary solenoid and 7-turns secondary solenoid are fabricated in silicon wafers, where the two intertwining solenoids are located at inner deck and outer deck, respectively. Permalloy soft magnetic core is inserted into a pre-etched channel in the silicon chip, which is surrounded by the solenoids. The size of the chip-style transformer is as small as 8.5 mm × 6.6 mm × 2.5 mm. The internal resistance of the primary solenoid is 1.82 Ω and that of the secondary solenoid is 0.16 Ω. The working frequency of the transformer is 60 kHz. Combined with the testing circuit of the switch mode power supply, the DC voltage of 13.02 V is obtained when the input is 110 V at 50 Hz/60 Hz. Furthermore, the on-chip 3D solenoidal transformer is used for lighting four LEDs, which shows great potential for AC-DC power supply. The wafer-level fabricated chip-style solenoidal AC-DC transformer for integrated power supply is advantageous in uniform fabrication, small size and volume applications.
