Industry – Driving Industrial BLDC Motor with Diotec’s DIW120SIC028

The electrification of our environment is becoming more widespread every day, reflecting the growing demand for more environmentally friendly and sustainable energy sources. As a result, electric motors are becoming increasingly important in this transition. Whether implemented with BLDC or AC motors, their versatility is remarkable, from cooling your body perfectly on a hot summer's day to powering your fancy electric vehicle for your daily commute. However, the biggest question remains: how can we further improve our ability to efficiently drive extremely large amounts of energy for these highly demanding applications?

Traditionally, designers would always choose to parallel 2 or 3 MOSFETs together. However, in most cases, when driving BLDCs with the conventional MOSFETs, this approach would often require a certain level of circuit complexity, as they need to be turned on simultaneously to avoid any further complication. In this scenario, two options could be suggested: Driving from a single unified gate drive or individual gate drives for each of the MOSFETs. The latter would increase the overall cost of the circuit, while not proving to be effectively better, as the designer would still have to overcome the propagation time between them. Therefore, the former method is preferred in most cases. In addition, paralleling MOSFETs is not as simple as it sounds, as many factors need to be taken into account, such as selecting an appropriate gate resistance and implementing a snubber circuit to suppress the effect of stray inductance in the PCB. If not implemented correctly, it could cause internal destruction due to the uneven load distribution and threshold voltage deviation expected from its "positive temperature coefficient" nature. Save yourself the headache and opt for our exclusive new DIW120SIC028 which could be your potential missing piece of the puzzle and driving the ever increasing power demanding BLDC motor would never be difficult.

Powering Data Safety: The SK220SMA Advantage!

2 A / 200 V Schottky in DO-214AC/SMA for Server Backup Supplies

Data servers are on duty 24/7, allowing us to communicate whenever we want, but also ensuring that all our electronic-based daily lives run smoothly and safely - and that's not all we could think of. A failure in the server supply can cause expensive losses and, in the worst case, lead to critical situations - just think of emergency calls, health services or air traffic control. For this reason, server stations are always equipped with a battery back-up, operating on either 24 V or 48 V DC.

The battery management and charging circuit is controlled by low-voltage electronics at 5V or even 3.3V, the typical supply voltage for microcontrollers. These supply voltages must be generated from the higher battery levels. As the circuits operate in stand-alone mode without human intervention, there is no need to use isolated switching topologies. A simple step-down or buck converter can do the job with high efficiency and the required reliability. It consists of a MOSFET and a so-called buck diode, usually a Schottky. These are chosen for their low forward voltage drop and low switching losses.

As a rule of thumb, the safety margin between the DC voltage and the allowable Schottky reverse voltage should be between three and six times the DC level. Only then can reliable operation be guaranteed, ensuring that potential voltage spikes remain well below the maximum ratings of the Schottky diode. The SK220SMA by Diotec Semiconductor is a high voltage Schottky diode offering an admissible reverse voltage of 200 V and forward current of nominal 2 A. It comes in the small yet powerful DO-214AC/SMA case outline measuring just 5 by 2.7 mm. Forward voltage drop is less than 950 mV at 2 A, and reverse leakage below 50 µA at 200 V, all at 25°C. This makes the parts ideally suited as buck diodes used in battery back-up systems of data servers.

Diotec Unveils DIW065SIC015: High-Efficiency 650V SiC MOSFET with Ultra-Low 15mΩ RDS(on) in TO-247-3L

Diotec Semiconductor introduces its latest Silicon Carbide (SiC) MOSFET, DIW065SIC015, featuring the lowest RDS(on) values in its portfolio at 15 mΩ. It is encapsulated in the classic and familiar TO-247-3L package, which is easy to implement in the circuit design of any high power application. This part is ideally suited for high efficient, high frequency power supplies used in server stations. In addition, it can cover a comprehensive portfolio of various applications like Photovoltaic Inverters, Industrial Machinery and Power Conversion Systems.

In power electronics, industries are striving to deliver higher power while maintaining or improving overall efficiency. Enter SiC, the next-generation technology that is making waves, outshining its traditional predecessor, Si-based power MOSFETS, with its superior voltage breakdown and significantly reduced power dissipation. The use of wide bandgap technology allows these devices to operate reliably in high temperature environments. In addition, with faster switching times, SiC MOSFETs exhibit lower switching losses per cycle, thereby improving efficiency and maintaining higher switching speeds in power conversion systems. As a result, SiC MOSFETs are emerging as the primary solution for a wide range of applications, particularly those involving high-voltage switching at higher frequencies where Si-based IGBTs are limited.

Diotec’s High Power Discretes –Supporting a Reliable, Modern Energy Supply

Discrete power semiconductors play an important role in modern energy supplies. Electrical energy is transported and distributed over wide distances using alternating current (AC). Wind and water turbines but also traditional power stations generate such AC current. Photovoltaic (PV) plants and battery storage systems operate in contrast at direct current (DC) levels. The growing fleet of electric cars can be used as a huge "virtual" energy store: During sunny or windy days, when a lot of excessive energy is available, EVs connected to public charging piles can collect that energy in their batteries. At home and connected to the private wall box, the electricity can be used by the owner or fed back into the mains.

But how does it work? On common electricity mains, bridge rectifiers are used to convert AC into DC. Silicon Carbide (SiC) MOSFETs create from such DC rails high frequent PWM signals, which then are transferred via transformers to the required battery level. SiC Schottkys rectify again that high frequent signal into a DC power output. As such, excessive energy can be stored in the on-board batteries. When it comes to feeding back the electricity to the mains, a similar concept is used to transfer the DC energy from the battery into the AC line.
