Rola Transformerên di Circûtkan Voltage Multiplier de

Transformeran rôla yekêmîn dibejîn di circûtkan voltage multiplier de, bêlî ji ber vegerî nekare çendkirina voltage. Circûtkan voltage multiplier pirî jî transformeran bi elementên rectifying (wisa diod û capacitor) bêrbin hêsan dikarin çendkirina voltage an jî dujîn bike. Li jêr şevazandin rôla transformeran di circûtkan voltage multiplier de û çawa bikaranîna du transformer da dibeke voltage output zêde bike.

1. Rola Basetî Transformeran

Step-Up/Step-Down Voltage: Transformeran dikarin voltage input zêde û ya wekîn bike. Bi hilbijartina rastînîn ratio (ratio ya turns primary û secondary winding), transformasyon voltageya xweşdibin dikare were çewtîn.

Isolation: Transformeran jî isolation elektrikê dan, ku bêlî qablanîn elektrik direct yên di navcircût û output circuits de bêrnavkirina tune, li sera wê re safety û reliability zêde bike.

2. Prînsîp Basetî Circûtkan Voltage Multiplier

Circûtkan voltage multiplier bikaranîna stagesên çendkirina rectification û filtering dikarin bikin bêrha voltage multiplication. Cûre types of voltage multiplier circuits include:

Half-Wave Voltage Doubler:

Yek diode û yek capacitor bikar bînin bêrha voltage di her half cycle de dujîn bike.

Voltage output pêşîn dikare wekî twice peak input voltage be.

Full-Wave Voltage Doubler:

Bikaranîna diodes û capacitors ên din dikare bêrha voltage di her complete cycle de dujîn bike.

Voltage output pêşîn dikare wekî twice peak input voltage be.

3. Bikaranîna Du Transformeran bêrha Zêdetir Output Voltage

Heta transformer yek dem dikare step up voltage, bêlî çendkirina output voltages zêdetir, metoda wan jî berbargirîne:

Method One: Series Connection of Transformers

Prînsîp: Connecting the secondary windings of two transformers in series can double the output voltage.

Connection Method:

Connect the positive terminal of the first transformer's secondary winding to the negative terminal of the second transformer's secondary winding.

The output voltage is the sum of the voltages from the secondary windings of both transformers.

Method Two: Cascaded Voltage Multiplier Circuits

Prînsîp: Adding multiple stages of voltage multiplier circuits to the output of a transformer can further increase the output voltage.

Connection Method:

Use a transformer and a voltage multiplier circuit in the first stage to double the voltage.

Use another transformer and a voltage multiplier circuit in the second stage to double the voltage again.

Mînak

Assume an input AC voltage of 120V RMS, and we want to increase the output voltage using two transformers and voltage multiplier circuits:

First Stage:

Use a transformer to step up the input voltage from 120V to 240V.

Use a full-wave voltage doubler to double the 240V peak voltage (approximately 339V) to 678V.

Second Stage:

Use another transformer to step up the 678V to 1356V.

Use another full-wave voltage doubler to double the 1356V peak voltage (approximately 1916V) to 3832V.

Pêşgotiya

Rola Transformeran: Transformeran di circûtkan voltage multiplier de bêyîn bêtirîn bikaranîn bêrha step-up û step-down voltage û bêrha isolation elektrikê dan.

Zêdetir Output Voltage: Output voltages zêdetir dikare bêrha connecting transformers in series û bêrha cascading voltage multiplier circuits were çendkirin.

Bikaranîna du transformeran û voltage multiplier circuits dikare bêrha zêdetir output voltage, bêlî jî complexity û cost of the circuit zêde bike. Additionally, it is essential to ensure that all components can withstand high voltages to ensure the safety and reliability of the circuit.
