At 3 a. m. , the plant's production line remained high.
In the server room, thousands of equipment continue to export data; before the new energy vehicle is charged with a pole, the current is rapidly converted; and the home television, air-conditioning, intelligence equipment is also consuming stable electricity in silence.
You may not know that there is a key device behind these devices – MOSFET.
It is like a “high-speed switch” in a circuit, with thousands of openings and shut-downs per second, and it accurately deploys, converts and controls electrical power.
And in high-voltage power systems, this little chip is more challenging:
How to withstand high voltage shocks and how to reduce switch losses? How can long-term stabilization be achieved in high-temperature, high-frequency environments?
This is exactly the direction of the continuous breakthrough of the MoS at MOT pressure level.
PART. 01
In high-pressure environments, stability is real power.
Pressure resistance is the first test for power semiconductors.
A voltage surge may render normal devices ineffective; a long-term high-temperature operation may also affect the lifetime of the equipment.
The Pyramid MOT Plateau MOS series of products, covering a wide range of high-pressure applications, can be used in such areas as switches, LED lighting, adaptors, industrial controls, and communications power sources to provide stable and reliable solutions for different power levels.
From the hundreds of voltage platforms to the distribution of higher stress-resilient products, MOT continuously refines the high-pressure MOS product matrix, giving engineers more flexible choice space in different applications.
PART. 02
It's not just stress tolerance, it's efficiency.
Many people think that the MOSFETs is simply a “capable switch”.
But for engineers, what really determines systemic performance is the details hidden behind the parameters.
1 RDS(on): Decision on leading loss or loss
The power loss occurs when the MOS is channeled:
P=I2xRDS(on)
Lower conductive resistance means lower heat and more efficient conversion.
In high-power applications, every drop in RDS (on) can lead to a decrease in system temperature and energy efficiency.
2 Qg: determine switch speed
In high-frequency power, MOS needs to quickly complete switch action.
The smaller the grid charge Qg, the lower the driving wear and tear, the faster the switch, the more suitable for the high frequency working environment.
Excellent Qg design can help power systems to reduce losses and improve overall efficiency.
3. Switch losses: key to efficiency gains
In the course of the MOS process, the opening and closing occurs with dynamic wear and tear.
Switch losses relate mainly to:
Switch frequency Fs
• Fence chargeQg
: : Rise/downtime
Drive currents
These factors are relevant.
Therefore, high pressure MOS requires not only “capacitating the voltage”, but also “toggle fast enough”.
MOT MOS
In the face of unusual shocks, reliability is the bottom line.
Practical application environments are not always ideal.
Power start-ups, the release of energy from telepathic circuits, and load mutations can generate transient shocks.
Therefore, MOS devices need to have good:
• SOA (safe working area)
Avalanche tolerance
• Thermal stability energy
Ensure that equipment remains reliable under complex conditions.
The MoS is designed with a mature process platform, continuously optimized in terms of consistency, reliability and long-term stability of operations, providing a more secure power device selection for clients.
From a chip to the future of an industry.
Today, energy conversion efficiency, from the consumption of electronics to industrial equipment, from intelligent household electricity to new energy applications, is becoming an important indicator of industrial competition.
MOSFET is an important element in improving efficiency.
It has been focused on power semiconductor areas, adheres to product innovation and quality control, continuously enriches the MOS product series and provides stable, efficient and reliable power solutions for global clients.
In the future, power semiconductors will assume an increasingly important role as new energy sources, intelligent manufacturing and the digital economy develop rapidly.
