Description
Tieto nedostatky odstraňuje zapojenie pulzačného meniča s nabíjacím tyristirim, kde ku kladnému pólu zdroja je připojená anoda hlavného tyristora a anoda vypínacieho tyristora. Katoda hlavného tyristora je spojená s jedným polom komutačného kondenzátora, katodou nulovej diody a jednou svorkou spotřebiče. Druhý pól komutačného kondenzátora je spojený s jedným koneom indukčnosti. Druhý koniec indukčnosti je spojený s katodou vypínacieho tyristora a anodou nabíjacieho tyristora. Druhý koniec spotřebiče je spojený e anodou nulovej diody, katodou nabíjacieho tyristora a záporným polom zdroja. Podstata vynálezu spočívá v tom, že anoda oscilačnej diody je spojená s anodou hlavného tyristora.These drawbacks are eliminated by the connection of the pulsation converter with the charging thyristor, where the main thyristor anode and the trip thyristor anode are connected to the positive pole of the source. The main thyristor cathode is connected to one commutating capacitor field, a zero diode cathode and one appliance terminal. The other pole of the commutation capacitor is connected to one end of the inductance. The other end of the inductor is connected to the tripping thyristor cathode and the charging thyristor anode. The other end of the appliance is connected by a zero diode anode, a charging thyristor cathode and a negative source field. The principle of the invention is that the anode of the oscillating diode is connected to the anode of the main thyristor.
Pokrok zapojenia pulzačného meniča s nabíjacím tyristorom je predovšetkým v tom, že zapojením oscilačnej diody do obvodu komutačného kondenzátora sa vypínací proces urýchli a je prakticky nezávislý od závažného prúdu. Činnost meniča sa nenaruší ani pri krátkodobou přetažení, ani pri přerušovaní obvodu k spotřebičů.In particular, the advancement of the connection of the pulsation converter with the charging thyristor is that by connecting the oscillating diode to the commutating capacitor circuit, the tripping process is accelerated and is virtually independent of the severe current. The operation of the inverter is not interrupted during short-term overloading or when the circuit to the appliances is interrupted.
Na připojených obrázkoch sú dve konkrétné riešenie zapojenia pulzačných meničov ε nabíjacím tyristorom podía vynálezu. Na obr. 1 je zapojenie pulzačného meniča s nabíjacímIn the accompanying figures, there are two particular solutions for the connection of the pulsation converters ε by the charging thyristor according to the invention. In FIG. 1 is a charging pulse converter

200 630 tyriatorom. Na obr. 2 je zapojenie pulzačného meniča s nabíjecím tyristorom a s závěrně vodivým tyristorom.200 630 thyriator. In FIG. 2 is a pulse transducer with a charge thyristor and a conductive thyristor.
Zapojenie podía vynálezu na obr. 1 pozostává z jednosměrného zdroja 1, vypínacieho tyristora 2, komutačného kondenzátora 2» indukčnost! 4, nabíjacieho tyristora 2« nulovej. diody 6, spotřebiče 7, Plavného tyristora 8 e oscilačnej diody 9· Zapojenie podía vynálezu ne obr. 2 je ako ne obr. 1, ale namiesto hlavného tyristora 8 a oscilačnej diody 9 se i-stor 10.The circuit according to the invention in FIG. 1 consists of a unidirectional source 1, a tripping thyristor 2, a commutating capacitor 2 »inductance! 4, the charging thyristor 2 ' The diodes 6, the appliances 7, the floating thyristor 8 and the oscillating diode 9. 2, as in FIG. 1, but instead of the main thyristor 8 and the oscillating diode 9, i-stor 10.
.yuálezu je nasledovná. Súčastným zapnutím hlavného tyristora a nabíjacieho -^stora b začne pretekaí záíažný prúd do spotřebiče 7. Súčastne sa nabije komutačný kondenzátor 2 cez indukčnosť 4 a nabíjecí tyristor 5· Zapnutím vypínacieho tyristo ra 2 záťažný prúd postupně komutuje z hlavného tyristora 8 na obvod vypínacieho tyristora 2, ktorý pozostává z vypínacieho tyristora 2, indukčnosti 4, komutačného kondenzátora 2» použije závěrně vodiv Činnosť zapojen..yuálezu is as follows. By simultaneously switching on the main thyristor and charging chamber b, the load current flows into the appliance 7. Simultaneously, the commutating capacitor 2 is charged via inductance 4 and the charging thyristor 5 is switched on by switching on the trip thyristor 2. which consists of a tripping thyristor 2, an inductance 4, a commutating capacitor 2, will use a closing conductor.
spotřebiče 7 a na obvod nulovéj diody, ktorý sa skládá z nulovéj diody 6 a spotřebiče 7.and a zero diode circuit consisting of a zero diode 6 and an appliance 7.
Na obr. 2 je óalšia varianta podía vynálezu, ktorého činnosť je rovnaká ako na obr. 1, len hlavný tyristor 8 a oscilačná dioda 2 je nahradená závěrně vodivým tyriatorom 10.In FIG. 2 is another variant of the invention, the operation of which is the same as in FIG. 1, flax main thyristor 8 and oscillating diode 2 are replaced by a conductive thyriator 10.
Uvedené zapojenia pulzačných meničov možno použiť věade tam, kde sa vyžaduje regulácia jednosměrného prúdu v širokých medziach. Vyeoká spoíahlivosť sa dosiahne s riadením pri konštantnej frekvencie periody spínania. Komutačný kondenzátor aa nabíja vždy na rovnaká napatia, ktoré je o mnoho vačšie než napatie zdroja. Prebitie komutačného kondenzátora na opa čnú polaritu pri vypínacom procese nezávis! od záťažného prúdu. Měnič pracuje s vysokou spoíahlivosťou. Z chodu nevypadne ani pri odpojení záťaže od spotřebiče ani pri krétkodobom skrate na spotřebiči. Hlavné použitie je pri riadení jednosměrných strojov.Said pulse transducer connections can be used wherever DC current regulation is required within wide limits. High reliability is achieved with control at a constant switching period frequency. The commutation capacitor aa always charges to the same voltage, which is much greater than the voltage of the source. Overloading the commutation capacitor to the opposite polarity in the tripping process is independent! from the load current. The inverter operates with high reliability. It does not fall out of operation when the load is disconnected from the appliance or when the appliance is short-circuited. The main use is in the control of unidirectional machines.
