“…In 1998, a hybrid current-limiting interrupting device (HCLID) was proposed by experts at the Technical University of Gdansk, Gdansk, Poland. The structure of the HCLID is simple: a mechanical contact, two diode and two thyristors, together with an L-C series-connected circuit [31,32]. As seen in Figure 11, the HCLID may inject a countercurrent into the main path to provide zero-crossing conditions.…”

Circuit breakers (CBs) are the main protection devices for both alternating current (AC) and direct current (DC) power systems, ranging from tens of watts up to megawatts. This paper reviews the current status for solid-state circuit breakers (SSCBs) as well as hybrid circuit breakers (HCBs) with semiconductor power devices. A few novel SSCB and HCB concepts are described in this paper, including advantage and limitation discussions of wide-band-gap (WBG) devices in basic SSCB/HCB configuration by simulation and 360 V/150 A experimental verifications. Novel SSCB/HCB configurations combining ultra-fast switching and high efficiency at normal operation are proposed. Different types of power devices are installed in these circuit breakers to achieve adequate performance. Challenges and future trends of semiconductor power devices in SSCB/HCB with different voltage/power levels and special performance requirements are clarified.

“…The resulted impedance is resistive so that the fault current is in phase with the voltage [17]. The experts in Technical University of Gdansk proposed their hybrid current-limiting interrupting device (HCLID) in 1998, with the configuration of L-C counter current injection circuit [29,30], as shown in Fig. 11.…”

This paper presents a survey of topology configurations of current-limiting circuit breakers. Twelve different current-limiting topologies within four categories are detailed discussed and compared. It is concluded that active CL-CB may be a good choice for AC for its controllable reactive power capability to increase stability and multi-function protection.
“…Łącznik stanowi aparat zaliczany do rodziny ograniczników prądu FCL (ang. Fault Current Limiter), których działanie polega na szybkim i samoczynnym włączaniu do obwodu zwarciowego reaktancji w układzie jednofazowym lub trójfazowym [2,3,5]. Inne znane i od lat rozwijane techniki FCL polegają m.in.…”

“…W pełni tyrystorowy wyłącznik ograniczający [5] powstał jako rozwinięcie idei układu hybrydowego, w którym funkcje ograniczania i przerywania prądu były rozdzielone. Wyłącznik hybrydowy o strukturze szeregowej z dwoma dławikami ograniczającymi [2] opracowano na Wydziale Elektrycznym Politechniki Gdańskiej. Podjęta tematyka wpisuje się w widoczny od szeregu lat trend stosowania półprzewodnikowej aparatury FCL [8].…”

“…Ograniczniki tyrystorowe [2] i [5] wymagają stosowania wielkogabarytowych dławików i odznaczają się znacznymi stratami mocy w stanie przewodzenia, jednak w szczególnych sytuacjach korzyści z ich zastosowania przeważają nad wadami, np. : podczas badań laboratoryjnych modeli lub prototypów urządzeń z przekształtnikami energoelektronicznymi.…”

Based on literature study of known thyristor limiters and the modification providing of a low current switch function was presented. The proposed DC/DC inverters for control and temperature indirect independency was described. Preliminary results of one phase switch circuit simulation are included. In summary succession problems of application was shortly pointed out.
