Igbochi oscillator: ụdị, ọrụ ụkpụrụ

Igbochi oscillator - na-na ntụrụndụ usu generator na-rụrụ dabeere na ya ihe ana-akọwa mmewere (e.g., transistor) na a siri ike nzaghachi transformer. The ọtụtụ ugboro ugboro na-eji mma nzaghachi.

The uru nke ndị dị otú ahụ generators-atụle ga-dịtụ mfe, ike jikọọ ibu site transformer. Udi nke na site pulses bụ nso akụkụ anọ, esịmde ọtụtụ iri puku ndị ọrụ okirikiri, ogologo - narị microseconds. The ịmachi usu ugboro ugboro ugboro ruo ọtụtụ narị kHz. Ike oscillatory na sekit na sekit na ndị dị otú ahụ na ngwaọrụ dị obere, na-kpatara interturn capacitances, n'ezie, echichi ikike. N'ihi na nke a àgwà igbochi oscillator na ọtụtụ-eji imewe nke: na akpaaka ngwaọrụ, ulo oru na ụkpụrụ ngwá electronic.

Na mwepu nke ndị a generators bụ na nduzi nke ugboro nke mgbanwe ndị na-ọkọnọ voltaji. The kwụsie ike nke ugboro bụ ala karịa nke multivibrator bụ naanị 5-10 percent.

Igbochi oscillator, anakọtara site na mma okporo ụkpụrụ ma ọ bụ na a resonant circuit na na-na-ekiri ka ugboro nke usu ugboro ugboro, na a kpochidoro diode, nwere a dịtụ elu kwụsie ike nke oscillation. Frequency kwụsie ike dị otú ahụ na nkata, na-erughị otu percent.

Igbochi oscillator, ọrụ ụkpụrụ

Ọrụ nke circuit ekewa n'ime ọtụtụ nkebi. Nzọụkwụ Otu: akpọchi transistor na-adị mgbe abanye usu na emitter. The ngwaọrụ amalite na-arụ ọrụ. Mgbe ndị isi nke transistor enweta a ụzọ ámá ugbu a, ọ na-akpata ihe-ndebe ìgwè na-abawanye nke na mkpoko ugbu a. Site resistor bụ mma nzaghachi, emejuputa windings nke usu transformer excites ndị nnukwu usoro ibu isi, na mkpoko okwukwo na ibu ugbu a. Nke a mbelata a nwere ihe dị iche n'etiti emitter na mkpoko nke transistor mgbe ọ esịmde efu, na unit abatakwa a saturation ala. Nzọụkwụ abụọ: eleghara isi asọfe eguzogide, anyị kweere na eriri igwe bụ nyere na DC voltaji. N'ihi ya, ndị fọdụrụ windings nke transformer voltaji bụkwa agbanweghi agbanwe. Agwa mgbanwe circuit okwukwo kpebisiri ike site onwunwe nke ígwè na-ejikọrọ na usoro na abụọ windings, nakwa dị ka Njirimara nke transformer isi. Ka ihe atụ, na nke ugbu a ga-adị mgbe niile resistive ibu. Ugbu na ndabere nke a mgbe nile nke transistor, ma na-amalite ibelata mgbe ichaji capacitor. The mkpoko ugbu a kpebisiri ike site na nchikota nke magnetizing ugbu a na-akwụsị akwụsị ugbu windings. The magnetizing ugbu a na-abawanye, ibu hysteresis loop kpebisiri ike site ọdịdị nke isi ihe. N'ihi ya, na-abawanye na nke ugbu a mkpoko. Nke a na-eme ka transistor abịa nke saturation, na usu elu a kpụrụ. The mkpoko ugbu a bụ ọzọ dabere na ịdị ukwuu nke isi ụgwọ, na isi ugbu a nnukwu-amalite ibelata. Transistor ekpochi, usu ngalaba a kpụrụ. Mgbe kpochidoro ngwaọrụ igbochi oscillator amalite naghachi ya mbụ ala.
