From the implemented prototype, a wide range of 150–450 V in output voltage is observed. The converter achieves an efficiency of 95.4% and can be applied as single-stage on-board charger or as PFC converter with variable DC link voltage in two-stage converter operation.
The control structure in these converters uses a two mode operation based on input and output voltage. If the output voltage is greater than the peak of input voltage, the converter operates in step-up mode. If the output voltage is less than peak of input voltage, then the converter operates in step-down mode [ 24 ].
The converter output voltage is maintained at 200 V with low-line input, the OBC always operates in step-up mode and have the duty ratio times the input current at switch . is always on in this mode and current through it is a bit higher than that of but less than the input current flowing through inductor .
It should be noted that the high voltage gain boost converter has lower power conversion efficiency. Therefore, it usually needs two battery cells in series instead of in parallel in order to achieve high power conversion efficiency for the DC-DC regulators. See the information detailed battery selection based on structure, capacity and safety..
The output impedance of the battery is ZOUT and the input impedance of the DC-DC converter is ZIN, as depicted in Fig. 23. VBAT is the open-circuit battery voltage. The battery impedance ZBAT includes DC resistance and AC resistance. Fig 23. Impedances at the interface of two subsystems.
In other words, two-mode operation (step-up or step-down) converters are the most suitable candidates for the application. However, there is a perception that single-stage non-isolated converters inherently contains low frequency ripple (LFR), i.e. twice the fundamental which can degrade the performance of battery during charging.
