Low Power and Voltage Applications span from a few watts to tens of watts with output voltages between 12 and 48 V, commonly used to power sensors, small communication devices, low-demand devices like LED lighting, and to adjust the output of small residential fuel cells (24–48 V) to align with the microgrid's voltage.
The voltage stress on the power switches is minimal, allowing for the use of low-voltage-rated switches with decreased on-resistance. This choice helps to mitigate conduction losses and ultimately enhances the total efficiency of the system.
To manage the voltage gain of the configuration, the proffered design offers two adjustable parameters: the duty cycle of the power switches and the turns ratio of the CIs. This flexibility in design allows for effective control over the converter's voltage gain.
