The main components required for linear power supply design include:
Liniowy zasilanie zasilanie charakterystyka
Liniowy zasilanie zasilacze typowo konwersja AC napięcie z różne elektroniczne urządzenia na niższe DC napięcie. The AC sieć napięcie jest zwykle 120V@60Hz lub 220V@50Hz Then, it is converted to converted to converted to the required DC voltage through a linear power supply. Linear power modules can provide fixed arbitrary DC voltage or various voltages ( plus 5, plus 12, -12 V) for larger circuits. Oni mogą również tworzyć bipolarne napięcia, takie jak ± 15V for operacyjne wzmacniacze lub dual tracking power supply with mutually locked voltage. The common uses of linear power sources are communication systems, amplifiers, laboratory testing equipment, various control circuits, and high-power industrial equipment. Examples of linear power output voltage include:
Podłącz do do głównej zasilania zasilania przez przełączniki% 2c bezpieczniki% 2c lub wskaźnik światła. Zapewnij dobre uziemienie i izolacja z dowolnego odsłoniętego przewody z tulejami do ochrony moc zasilanie.
A transformer with turns and structure based on the required output voltage. This is used to isolate the remaining parts of the downstream circuit from power reference. Transformers may have multiple taps to allow different power input voltages and secondary taps to obtain the required output voltage. Some transformers may have a copper foil shield between the primary and secondary taps to reduce capacitance coupling to high-frequency power source noise.
A prostownik że konwertuje AC sygnały na DC. Ogólnie mówiąc, a full wave bridge rectifier is the most is most ensure that the diode you choose has been carefully calculation. The use of inways or small diodes may lead to failures caused byd expulsive overpress s. Choosing diodes with peak reverse voltage may also helpful in add to use longer leads for better heat dissiped. Małe kondensatory can also be umieszczone in parallel for faster recovery.
Smooth kondensatory są używane do reduce the amount of AC ripple on the output quasi DC voltage of the rectifier. Capacitors with low equivalent series resistance (ESR), such as tantalum based capacitors, can better handle ripple.
