The market for industrial-use IGBT
modules is expected to grow at an annual rate of 3.5% from about 350 billion yen in 2018.*2 More and more large-scale wind power generation facilities are being constructed, particularly in Europe and China, and the global market for such facilities is expected to grow by 591 GW in 2018 and 8% annually by 2023 (source: GWEC).
In 2018, IGBTs
' global output value was about US$4.7 billion, with an annual growth rate of 16 percent, the research institute said.
The device co-packages a silicon-based IGBT
with a SiC Schottky barrier diode, resulting in an excellent tradeoff between the lower performance of silicon-based solutions and the higher cost of entirely SiC-based solutions.
modules are mainly used for such power conversion system and they are required to be compact, since many power components (e.g.
In the operation of buck mode, [S.sub.1] is the only main IGBT
used to transfer the output power and auxiliary IGBT
switch [S.sub.a] will turn-on before the main switch [S.sub.1] gets turned-off, in order to obtain zero current transition.
The stage on transistors Q7 and Q8 serves to amplify rectangular pulses in voltage and current sufficient for the key output stage operation on IGBT
transistors Q9 and Q10, Q11 and Q12 (IRG4PC50F), included in pairs in each arm of the push-pull circuit.
(i) Short-circuit faults affecting the IGBT
switches are the most serious faults.
and diode are integrated into a single chip, reverse-conducting IGBT
(RC-IGBT) requires the low acceleration and high concentration process to reverse P-shape part in the collector on the backside of the thin wafer to N-shape.
The state-of-the-art advanced IGBT
gate drivers target to improve the switching performances, and they can be classified as passive, open-loop and closed-loop types .
Total losses of Si IGBT
[T.sub.1] are the sum of conduction and switching losses; as a whole, the losses in the six Si IGBTs
of the inverter are six times higher, resulting in
The equivalent circuits of slip power recovery when the IGBT
is turned ON or OFF are shown in Figure 2, respectively.
* In event of overcurrent, driver initiates controlled switch shutdown with updating control with fault status, protecting the IGBT
