ON Semiconductor has further expanded its lineup of automotive power integration modules (PIMs) to introduce the STK984-190-E. The module is optimized to drive three-phase brushless DC motors (BLDC) for modern automotive applications, including six 40 V, 30 A MOSFETs configured as a three-phase bridge and an additional 40 V, 30 A high-side reversal Battery protection MOSFET. These MOSFETs are mounted on a direct-bond copper (DBC) substrate to create a compact module with excellent heat dissipation that occupies only half the board space used in a discrete solution with equal performance.
The module is suitable for 12 V automotive motor drive applications with rated power up to 300 W, such as electric pumps, fans and windshield wipers. Designers use a combination of motor controllers such as the LV8907UW to create an energy-efficient BLDC solution with best-in-class thermal performance and built-in diagnostics, and an ultra-small PCB that saves critical size and weight.
Using this module can significantly reduce component count and bill of material costs. The DBC substrate reduces the thermal resistance, which reduces the operating temperature of the MOSFET. This reduces power loss and enhances reliability by reducing temperature variations during thermal cycling. The insulation provided by the DBC substrate also increases reliability. The STK984-190-E specifies an operating temperature range of -40 ° C to 150 ° C. All integrated MOSFETs are AEC-Q101 certified.
Chris Chey, general manager of System Solutions at ON Semiconductor, said: "The development of an efficient BLDC drive solution typically requires at least 13 to 15 discrete components, while the STK984-190-E automotive power module requires less than half the components. In addition to compact Dimensions, STK984-190-E's rugged thermal performance supports the use of smaller heat sinks, which significantly reduces the size and weight of the system, which means that engineers can now fully meet the challenges of improving fuel economy and overcoming space constraints. â€
AC power supply is a kind of power supply that converts the input mains or DC input into a pure sine wave output after AC-DC-AC or DC-AC conversion. The ideal AC power supply is characterized by stable frequency, stable voltage, zero internal resistance and pure sine wave output voltage wave (without distortion). Mainly used for power grid simulation tests conducted by various electrical appliance manufacturers on electrical appliances according to the voltage/frequency requirements of different countries, various AC motors, AC transformers, aircraft & mechanical equipment and other electronic devices that require pure, regulated and frequency-stabilized output.
Our AC power supply mainly includes three types
1. AC Power Supplies converting the input mains AC by AC-DC-AC, output voltage and frequency are stable and adjustable with pure sine wave output waveform, so called: Variable Frequency AC Power Supplies.
2. AC Power Supplies converting the DC output of the battery and other DC equipment by DC-AC, giving an AC sinusoidal output with stable output voltage and frequency. so called: Inversion AC Power Supplies.
3. AC Power Supplies converting the input mains AC by AC-DC-AC, giving a variable voltage AC output at constant 400Hz output frequency ultra-high output frequency stability. so called: Intermediate Frequency AC Power Supplies.
4. According to the difference in the number of output phases, the AC Power Supplies can be divided into single-phase output AC power supplies and three-phase output AC power supplies.
Different from Variac and AC voltage regulators, our AC power supplies support the setting of output voltage and frequency and has superior high precision, high stability, and high efficiency stable frequency AC output, not only for AC power conversion but also for AC high precision test purpose.
Through the friendly operation panel, you can read the output data such as output voltage, output current, output power, power factor, etc., providing accurate data records for your test, and can add RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies.
Our AC Power Supplies have comprehensive protection functions, such as: over voltage, over current, over temperature and short circuit protections, which can protect the AC power supplies and DUT from damages.
