| Popis: | In today’s industrial systems, especially at low power applications, since they have simple structure and easy control, flyback converters are preferred. Furthermore, with suitable for multiple output levels on one device, be able to respond to different power demands, simple installation, eligibility of cost requirements, isolation between the inputs and outputs of the circuit structure, compliance with default safety standards and such advantages have been preferred. Although they have these advantages, flybacks suffers from leakage inductances. They cause high voltage spikes and extra losses. In our circuit model based on flyback topology, contribute to work on the circuit by eliminating the losses as much as possible, for feeding devices that require different voltage values with a single power supply, and increase efficiency by reducing voltage stress on the semiconductors and such improvements have been made. On the basis of these improvements, primarily classical circuit modeling has been done, all necessary numerical and analog measurements were presented. After that emphasis is placed on the increase in circuit efficiency with subsequent loss prevention improvements. 5 Voltage - 1 Ampere and 12 Voltage - 1 Ampere values, which are used in two separate and isolated output voltage sources are obtained. |
