PWM controller
Pulse Width Modulation (PWM) inoreva kushandiswa kwekubuda kwedhijitari kwemicroprocessor kudzora analogi wedunhu uye inzira yedhijitari kukodha chiyero chechiratidzo cheanalogi.Kudzora analog maseketi digitally kunogona kuderedza zvakanyanya mutengo uye simba rekushandisa kwehurongwa.Mazhinji microcontrollers ane PWM controller mukati mavo.
Principle
Tsanangudzo pfupi yemusimboti wePWM controller
Nheyo yekutanga yePWM kutonga yakavakirwa pachokwadi chekuti mapurusi akatetepa evhoriyamu yakaenzana uye maumbirwo akasiyana ane maitiro akafanana kana awedzerwa kune chinongedzo chine inertia.Pane nzira dzakasiyana dzekuisa pulse wide modulation, senge unipolar uye bipolar, synchronous uye asynchronous, rectangular wave modulation, uye sine wave modulation.Iyo unipolar PWM yekudzora nzira inoreva kuti iyo inotakura wave inongoshandurwa mune imwe nzira muhafu yekutenderera, uye iyo PWM waveform inongoshandurwawo munzira imwe chete, nepo bipolar PWM yekudzora nzira inoshandura iyo inotakura wave munzira mbiri muhafu yekutenderera. , uye iyo PWM waveform inoshandurwa zvakare munzira mbiri.Zvichienderana nekuti chiratidzo chekutakura chakawiriraniswa neiyo modulating chiratidzo, PWM control inogona kukamurwa kuita synchronous modulation uye asynchronous modulation.Rectangular waveform pulse width modulation inoratidzwa neinobuda pulse width column kuva yakaenzana nehupamhi, uye inogona chete kudzora imwe nhamba ye harmonics;Sine waveform pulse width modulation inoratidzwa neinobuda pulse width column, kwete yakaenzana nehupamhi, hupamhi hunoshanduka maererano nemutemo we sine, iyo yakabuda waveform iri pedyo nesine waveform.Sine wave pulse width modulation inonziwo SPWM.kuburitsa hupamhi hwekupuruzira zvinoenderana nechiratidzo chekudzora ndiyo kiyi yehunyanzvi uhu.Triangular waveform yekuenzanisa nzira, hysteresis loop yekuenzanisa nzira, uye space voltage vector nzira inowanzoshandiswa.

About Product
Iyo TL284xB uye TL384xB nhevedzano yekudzora yakasanganiswa maseketi inopa maficha anodiwa kuita off-line kana dc-to-dc yakatarwa-frequency ikozvino-modhi yekudzora zvirongwa, ine hushoma nhamba yekunze kwezvikamu.Maseketi akaiswa mukati anosanganisira undervoltage lockout (UVLO) uye referensi chaiyo iyo yakachekwa kuti inyatso pane yekukanganisa amplifier.Mamwe maseketi emukati anosanganisira logic yekuve nechokwadi chekushanda, pulse-width modulation (PWM) kuenzanisa iyo inopawo ikozvino-muganho wekutonga, uye totem-pole yekubuda nhanho yakagadzirirwa kuburitsa kana kunyura yakakwira-peak ikozvino.Iyo yekubuda nhanho, yakakodzera kutyaira N-channel MOSFETs, yakaderera kana iri kunze kwenyika.
Iyo TL284xB uye TL384xB yakatevedzana ipini inoenderana neyakajairwa TL284x uye TL384x nekuvandudzwa kunotevera.Iyo yekutanga-up ikozvino inotsanangurwa kuve 0.5 mA (max), nepo oscillator discharge ikozvino yakaderedzwa kusvika 8.3 mA (typ).Pamusoro pezvo, panguva yekuvhara kwekuvhara mamiriro, iyo inobuda ine yakanyanya saturation voltage ye1.2 V ichinyura 10 mA (VCC = 5 V).
Misiyano mikuru pakati penhengo dzeiyi nhevedzano ndeye UVLO zvikumbaridzo uye yakanyanya basa-kutenderera renji.Yakajairika UVLO zvikumbaridzo zve16 V (pa) uye gumi V (yakadzimwa) paTLx842B uye TLx844B zvishandiso zvinovaita kuti vanyatsokodzera kune off-line application.Iwo anowirirana akajairika makumbiriro eTLx843B uye TLx845B zvishandiso ndeye 8.4 V (pa) uye 7.6 V (yakadzimwa).Iyo TLx842B uye TLx843B zvishandiso zvinogona kushanda kune basa cycles inosvika zana%.Duty-cycle range ye0% kusvika 50% inowanikwa neTLx844B uye TLx845B nekuwedzera yemukati toggle flip-flop, inovhara kubuda kweimwe nguva yewachi yese. Iyo TL284xB-yakatevedzana michina inotaridzwa kushanda kubva - 40°C kusvika 85°C.Iyo TL384xB-yakatevedzana michina inotaridzwa kushanda kubva 0°C kusvika 70°C.
