Reverse Blocking IGCTs for Current Source Inverters
Using reverse blocking IGCTs in a CSI offers significant benefits compared to present GTO or thyristor solutions and allows higher inverter ratings and switching frequencies.

This paper proposes a new IMD based on a current-source inverter (CSI) topology that offers several performance improvements over existing IMD configurations.
Integrated motor drives (IMDs) can provide high power density, simplified installation, and easier retrofits for fixed-speed motors with adjustable speed drives (ASDs) in pump/fan applications.
A current source inverter is schematically shown in Fig. 1. Each of the positions can be a single switch or a series connection of several switches with small RC snubbers for voltage sharing.
Integrated motor drives (IMDs) can provide high power density, simplified installation, and easier retrofits for fixed-speed motors with adjustable speed drives (ASDs) in pump/fan applications.
In the last two (5.7-5.8) lessons in this module, the circuit and operation of different types of single-phase and three-phase Current Source Inverters (CSI), with waveforms, will be
As power semiconductor devices in current-source inverters must withstand reverse voltages, standard asymmetric voltage blocking devices such as power BJTs, power MOSFETs, IGBTs,
Current-source inverters (CSIs) using reverse-voltage-blocking (RB) switches were dominant in the early days of power electronics and are still used in some megawatt (MW)-level motor...
This paper presents the design consideration and development of a low inductance 3.3 kV silicon carbide (SiC) based reverse voltage blocking (RVB) half-bridge (HB) module for
Current source inverter (CSI) needs reverse-voltage blocking (RVB) switches and, historically, during the 1960s and 1970s, thyristors and gate turn-off thyristors were used [2].
