High zaus hloov hom fais fab mov khoom nta
High-frequency switching power supply (tseem hu ua switching rectifier SMR) ua hauj lwm ntawm MOSFET los yog IGBT. Kev hloov zaus feem ntau yog tswj tau nyob rau hauv qhov ntau ntawm 50-100kHz kom ua tiav kev ua haujlwm siab thiab miniaturization. Nyob rau hauv xyoo tas los no, lub hwj chim muaj peev xwm ntawm switching rectifiers tau txuas ntxiv nthuav dav, thiab ib chav tsev muaj peev xwm tau nthuav dav los ntawm 48V / 12.5A, 48V / 20A rau 48V / 200A, 48V / 400A. High-frequency switching fais fab mov yog ib qho kev hloov kho dua tshiab rau cov tshuaj rectifiers (silicon rectifiers, thyristor rectifiers). High-frequency switching power supplys sai sai nyob rau hauv lub lag luam vim lawv kiag li zoo xws li yooj yim ntawm kev siv, me me, high efficiency, ruaj khov, thiab cov txheej txheem zoo. Nws yog dav siv hauv electroplating, electrolysis, oxidation thiab lwm yam kev lag luam saum npoo, thiab tau txais kev qhuas los ntawm cov neeg siv khoom tshiab thiab qub.
Cov khoom no yog precision ua tiav siv cov khoom lag luam nto moo txawv teb chaws thiab thoob ntiaj teb qib siab tshaj plaws-bridge inverter converting thev naus laus zis, ua rau kev ua tau zoo ntawm tag nrho lub tshuab ruaj khov thiab zoo dua txhim khu kev qha. 2. Lub tshuab tag nrho muaj kev tiv thaiv tsis siv neeg lub tswb muaj nuj nqi thiab pib ua haujlwm mos rau overvoltage, overcurrent, overtemperature, luv Circuit Court thiab tsis muaj kev sib npaug. Thiab tuaj yeem nruab nrog lub sijhawm tswj thiab lub computer interface. 3. Lub DC tso zis waveform yog ib tug high-frequency square nthwv dej nrog ib tug ripple coefficient<1 [%], which can increase the number of plating, resist passivation, enhance the gloss of the coating surface and the core degree of the dark corners of the plated parts. It can also reduce the loss of raw materials and meet various special requirements of the electroplating industry. The 4SFG series adopts air-cooling design and is easy to install. And equipped with a remote control device, easy to operate. The machine can be switched on and off with load, reducing the cumbersome adjustment procedures. 5. Small in size and light in weight, the whole machine is manufactured using a full range of anti-corrosion processes, which enhances the anti-corrosion capability of the product and extends its service life. 6. Highly efficient and energy-saving, the working efficiency reaches more than 90[%], and any voltage-to-current ratio is always linearly matched. It eliminates the losses of the voltage regulator and main transformer of the traditional rectifier, saves more than 35% of energy, and greatly reduces the cost of electroplating. It is actually the most sensible choice in the surface treatment industry.
Raws li txoj cai tswj hwm TRC, muaj peb txoj hauv kev:
1. Pulse Width Modulation (pulseWidthModulation, abbreviated as) muaj lub sijhawm hloov pauv tas li thiab hloov lub luag haujlwm ntawm lub voj voog los ntawm kev hloov cov mem tes dav. 2. Pulse Frequency Modulation (abbreviated li pFM) muaj qhov ua haujlwm tas li pulse dav thiab hloov lub luag haujlwm lub voj voog los ntawm kev hloov pauv kev ua haujlwm zaus. 3. Hybrid modulation, ob qho tib si lub conduction mem tes dav thiab lub switching kev khiav hauj lwm zaus tsis ruaj thiab yuav hloov ib leeg. Nws yog kev sib xyaw ntawm ob txoj hauv kev saum toj no. High-frequency switching fais fab mov muaj peev xwm theoretically txo switching losses mus rau xoom yam tsis muaj ho nce lub switching ceev, thiab lub suab kuj yog me me.
