Abstract

This study presents the development and model of a DC voltage conversion circuit using series output modules with closed-loop control. To transform a low DC voltage into a high DC voltage. A voltage level transmitter circuit with limited gain has been created using traditional methods. The development included the use of the coupling Inductance technology, which entailed the addition of a coil L₂ to be linked with the original inductance coil L₁. This approach may enhance the output amplification by using operator the power modules are operated at a frequency of 90 kHz using a device that switches. Every power module is supplied with an input voltage of 36 volts and convert it into a voltage of 200 volts. A connection has been established in the power circuit. When connecting N modules in a series stack, the implement results will show an increase in voltage level. Consequently, the voltage is increased to 600 volts, generating an output power of 450 watts while operating at its full capacity. Using the proposed closed-loop control approach It is apparent that a change in electrical load occurs while changing from a no-load situation to a half-load one. at maximum load conditions. Consequently, the DC voltage output may revert again to the set value. The simulation findings and experimental results were found to be compatible. The analytical sequence may be verified based on theoretical principles.
