Functions of power semiconductors
The function of converting the power coming from various electronic devices to suit the corresponding electronic device,
the function of accurately and stably supplying the required power, high-voltage, high-current,
and high-speed switching semiconductor devices required for power conversion in the eco-friendly energy industry
(solar energy, electronic vehicles, power storage) and AI industry.
Diode
(Constant Voltage Diode SBD, FRD, etc.)
Convert alternating current to direct current through rectification function
Transistor / ICE
Amplification function / switching function
Bipolar Tr & IC
ON resistance is low /
but, the switching speed is slow
Suitable for high frequencies,
but has high ON resistance
MOSFET
Fast switching speed /
low power consumption /
easy miniaturization
Suitable for high frequencies,
but has high ON resistance
IGBT
Faster switching speed than Bipolar Tr.
Low power consumption /
easy miniaturization
Suitable for high frequencies and
has lower ON resistance than MOSFETs
Thyristor
(SCR, Trian, GTO etc.)
Special rectifying action
Uses and Applications of Power Semiconductors
Power semiconductors are characterized by higher voltage resistance, higher current,
and higher frequency compared to general semiconductor devices, and are used in most industrial machinery.
Diode
(Constant Voltage Diode SBD, FRD, etc.)
Automobiles, AV devices
Transistor / ICE
Industrial equipment, home appliances, and automobiles
Bipolar Tr & IC
Trend of being replaced
by MOSFET and IGBT
MOSFET
Expanding its use, including thin TV, motor drives, and high efficiency of power
IGBT
High growth expected in inverters for white goods, hybrid solar power generation,
and ESS applications
Thyristor
(SCR, Trian, GTO etc.)
Welders, direct current transmission, home appliances
