Block Diagram DC Power Supply

Electricity flows that we use in homes, offices and factories in general are generated, transmitted and distributed to the individual in the form of Alternating Current or AC current. But, electronic devices that we use today mostly requires a DC current at a lower

voltage for operation. Therefore, almost every electronics equipment have a circuit that functions to convert electrical current from AC current into DC current and also to provide the appropriate voltage to its Electronic circuit. Circuit that converts AC power into DC current is called the DC Power Supply. DC Power Supply is also commonly known as the "adapter". So we can find a dc power supply in any of our electronic equipment. The working principle DC Power Supply (Adaptor) on each block by block diagram above is the first from AC Voltage then to the Transformer, Transformer are used for the DC power supply is a transformer type of Step-down which serves to reduce the power supply voltage according to the needs of the component electronics contained in the circuit of the adapter (DC Power Supply). Although voltage has been lowered, the output of the transformer is still in the form of alternating current (AC) to be rectify. So we need the Rectifier, Rectifier is a series of Electronics in Power Supply that serves to convert the AC voltage into DC voltage after the voltage derived by Step down transformers. After the voltage to be the DC, In a series of Power supply need a filter, is used for leveling out of the current signal Rectifier. This filter usually consists of a capacitor component that type is ELCO (Electrolyte Capacitor). To generate voltage and DC current (direct current) are fixed and stable, required Voltage Regulator that serves to regulate the voltage so that the voltage output is not affected by temperature, load current and input voltage from Output Filter. Voltage Regulators generally consist of Zener diodes, transistors or IC (Integrated Circuit). So, DC Power Supply is device that converts AC power into DC current. DC Power Supply is used to electronic devices that we use today mostly requires a DC current at a lower voltage for operation.

Rectifier atau penyearah gelombang adalah rangkaian Elektronika dalam Power Supply (catu daya) yang berfungsi untuk mengubah gelombang AC menjadi gelombang DC setelah tegangannya diturunkan oleh Transformator Step down. Dalam rangkaian Power supply (Adaptor), Filter digunakan untuk meratakan sinyal arus yang keluar dari Rectifier. Filter ini biasanya terdiri dari komponen Kapasitor (Kondensator) yang berjenis Elektrolit atau ELCO (Electrolyte Capacitor). Untuk menghasilkan Tegangan dan Arus DC (arus searah) yang tetap dan stabil, diperlukan Voltage Regulator yang berfungsi untuk mengatur tegangan sehingga tegangan Output tidak dipengaruhi oleh suhu, arus beban dan juga tegangan input yang berasal Output Filter. Voltage Regulator pada umumnya terdiri dari Dioda Zener, Transistor atau IC (Integrated Circuit).
