Sic Mosfet

 

 

Silicon Carbide Metal-Oxide-Semiconductor Field-Effect Transistors (SiC MOSFETs) are type of power semiconductor devices that utilizes Silicon Carbide (SiC) as the semiconductor material. Silicon Carbide is a compound composed of silicon and carbon, and offers high thermal conductivity, wide bandgap, and high breakdown voltage. SiC represents the next generation of low-loss semiconductors, aiming to minimize switching losses and enhance performance, particularly in high-temperature conditions. This advancement enables the creation of smaller, lower power, and more efficient power devices compared to traditional silicon counterparts. SiC MOSFETs can reduce switching losses by fast switching due to theoretically no tail-current at switching operation. Low Ron with smaller die size, and low capacitance and gate-charge are achieved.

Advantages of Sic Mosfet
 

High Breakdown Voltage

Silicon carbide’s breakdown electric field is 10 times that of silicon, allowing the manufacture of smaller, higher-voltage SiC MOSFETs. This enables achieving high breakdown voltage while using thinner drift layers.

Current Density

SiC MOSFETs offer much higher current density than silicon MOSFETs, crucial for high-power applications.

High-Temperature Operation

Silicon carbide MOSFETs can operate at higher temperatures, allowing them to take advantage of higher current density without concerns about the device’s actual temperature.

Low Switching Losses

Silicon carbide technology gives SiC MOSFETs lower on-resistance, resulting in reduced conduction losses.

High Switching Frequency

SiC MOSFETs have a higher switching speed, allowing for the use of higher switching frequencies, thus reducing circuit size and costs.

Short Reverse Recovery Time

SiC MOSFETs have a fast reverse recovery time, in the range of tens of nanoseconds, much faster than silicon MOSFETs. This is crucial for improving circuit operation speed.

Structure of Sic Mosfet

 

 

Source

This layer is the source of electrons in the device and is typically connected to the negative terminal of the power supply.

 

Gate

The gate is the control terminal of the MOSFET, responsible for switching the device on and off. It controls the flow of electrons from the source to the drain.

 

Drain

The drain is the output terminal of the MOSFET, connected to the load in most power electronic applications.

 

 

Working Principle

When a positive voltage is applied to the gate terminal relative to the source, it creates an electric field that attracts electrons, forming a conductive channel between the source and drain terminals, allowing current to flow, making it the “on” state. Conversely, applying zero or negative voltage to the gate turns off the electric field, blocking current flow and placing the SiC MOSFET in the “off” state.

A: SiC devices provide lower on-state resistance and off-state leakage currents compared to silicon counterparts, resulting in enhanced efficiency. Additionally, they exhibit very low or negligible reverse-recovery current and can operate at three to five times higher system frequencies. This capability reduces the size and weight requirements of capacitors and magnetics.
