| Summary: | This thesis is about how power electronics can be implementing on embedded system program. Major in power electronics and controlling using embedded system is what the purpose of this project. This battery charger is supposed to be the fastest charging time among chargers that have nowadays. By using power electronics component that can handle big current and voltage this battery charger should be charging battery faster. Methodology that was use is SMPS topology that is Switch Mode Power Supply and using MOSFET as switching frequency. A switched-mode power supply, switching-mode power supply or SMPS, is an electronic power supply unit (PSU) that incorporates a switching regulator. The SMPS rapidly switches a power transistor between saturation and cutoff with a variable duty cycle whose average is the desired output voltage. The main advantage of this method is greater efficiency because the switching transistor dissipates little power in the saturated state and none in the off state. Other advantages include smaller size and lighter weight from the elimination of low frequency transformers and lower heat generation from the higher efficiency. Disadvantages include greater complexity, the generation of high amplitude, high frequency energy that the low-pass filter must block to avoid EMI, and a ripple voltage at the switching frequency. |
