Wannan rubutu ya nuna mafarin hanyar aiki na bridge rectifier.

Me ke Bridge Rectifier?

Bridge rectifier tana nufin alternator wanda ya canza AC input daga mains zuwa DC output. Bridge rectifiers sun bayar da DC voltage zuwa devices da components. Ana iya amfani da regulated solid-state switch (ko) four (ko) diodes da dama don in gudanar da su.

Load current ya nuna bridge rectifier. A lalace da rectifier power source don abubuwan da za a yi a electrical system, ana duba batun da ke

• Ratings da specifications da component,

• Breakdown voltage,

• Temperature ranges,

• Transient current rating,

• Forward current rating,

• Mounting requirements, da

dabam-dabam suna duba batun da ke.

Gudanar da Bridge Rectifier

Ana iya amfani da diodes D1, D2, D3, da D4 a wannan circuit, tare da load resistor (RL). Don in canza AC zuwa DC da kyau, ana iya gudanar da diodes a closed-loop arrangement. Manufar da ke da wannan design shine ya ba da kyau da special center-tapped transformer. Saboda haka, size da price zai rage.

Output DC signal zai iya samun da ita a cikin RL ba a bangaren da input signal an sanar da ita a kan terminals bi, kamar A & B. A cikin wannan halaye, ana haɗa load resistor a kan terminals bi, C & D. Ana iya gudanar da diodes bi a cikin yadda ake buƙata da bi da kuma biyu diodes zai ci gaba-gaban don in ci gaba-gaban. Diodes D1 da D3 zai ci gaba-gaban don positive (+) gaba-gaban. Diodes D2 da D4 zai ci gaba-gaban don negative (-) gaba-gaban.

Diagram na Circuit ta Bridge Rectifier

Center-tapped transformer full-wave rectifier ya ba da output voltage da ya kai da bridge rectifier. Saboda ba ya buƙata da center-tapped transformer, wannan circuit ya kai da less cost rectifier.

Diagram na circuit ta bridge rectifier ya ƙunshi levels da dama da components, ciki har zuwa

• Transformer,

• Diode bridge,

• Filtering, da

• Regulators.

Regulated DC power supply shine cewa duk building blocks bi da dama ake kira, kuma ya ba da damar ake sauyar da electronic equipment da dama.

1). Transformer

Step-down transformer wanda ya canza amplitude na input voltage ya ƙunshi initial stage na circuit. Yawan projects na electronics suna ci gaba 230V AC mains supply zuwa 12V AC supply da ake amfani da 230/12V transformer.

2). Diode Bridge

Na biyu shine diode-bridge rectifier, wanda, daɗi da kind of bridge rectifier, ana amfani da four (ko) diodes da dama. Considerations for the device, kamar Peak Inverse Voltage (PIV), forward current If, voltage ratings, etc., sun fi sune da kyau a lalace da diode (ko) switching device da dama don related rectifier. It is in charge of conducting a group of diodes for each half-cycle of the input signal in order to produce unidirectional (or) DC current at the load.

3). Filtering

Filtering ya fi sune don in samun output ba da diode bridge rectifiers a matsayin pure DC saboda pulsing nature. Idan wave ya rage, filtering ana iya yi da one (ko) capacitors da dama a kan load. Output voltage ya kasance da capacitor rating.

4). Voltage Regulators

Voltage regulator wanda ya ci gaba da output voltage ta kasance shine final step na controlled DC supply. Microcontroller ta run a 5V DC, amma bridge rectifier ta output 16V. Don in rage wannan value da kuma ci gaba da ta kasance bane idan input voltage ta rage, voltage regulator ya fi sune.

Principle na Hanyar Aiki na Bridge Rectifier

Four diodes ƙunshi single-phase bridge rectifier, wanda ya ƙunshi across the load kamar yadda ake bayyana.

D1 da D2 suna forward biased a Positive half cycle for AC input waveform diodes, amma D3 da D4 suna reverse biased. Load current takes when the voltage rises over the diodes’ threshold levels and they start conduct.

Diodes D3 da D4 suna biased forward a negative half cycle for AC input waveform, amma D1 da D2 suna biased backward. Idan D3 & D4 diodes suna faruwar canza, load current begins to flow through them.
