IMPROVING ISOLATED POWER MODULES WITH THE MID06W0505A SERIES
Power modules form a core part of power electronics applications. In particular, micro-power power modules are widely used to power various signal isolator applications, such as RS485, CAN, and RS232. Industry applications — such as industrial automation, electric vehicle battery management systems (BMS), and charging piles — continue to increase standards for safety, power density, and reliabilit...
COMPACT ISOLATED POWER MODULES: THE MID SERIES
MPS’s family of small, isolated power modules is perfect for biasing the digital isolators in RS485, RS232, and CAN communication, as well as other industrial and network applications. Higher channel density in PLC systems means less space per channel, making it critical for solutions to minimize board space. The MID power module family provides a tiny solution that integrates a transformer and a ...
FLYBACK VS. LLC POWER SUPPLIES: HIGH-VOLTAGE CONVERTERS SERIES
Isolated gate drivers are key parts of power converters, and require isolated power supplies to provide the gate driving voltage without breaking the isolation barrier. One of the most frequently used topologies for these applications is the flyback converter. However, increased leakage inductance caused by minimizing the interwinding capacitance loosens the coupling between the primary and second...
ISOLATED LLC TRANSFORMER DRIVER: MPQ18913
The MPQ18913 is a 30V, 6W, high-frequency, automotive LLC transformer driver for isolated bias power supplies. Designed for automotive and industrial applications, this solution can be used as a flyback replacement for biasing IGBTs and SiC FETs. LLC resonant topology enables minimal isolation capacitance, a much higher isolation voltage, and a higher switching frequency. With fewer required compo...
ISOLATED POWER CONVERSION FOR HIGH-POWER POWER SUPPLIES
MPS’s isolated high-power solutions enable power conversion for high-power power supplies. This example uses a 3kW AC/DC totem-pole power supply and an isolated LLC DC/DC converter. Featured components include the MPF32010 totem-pole controller, MP18831 isolated gate driver, MID1W0505A isolated power supply, MPF32020 LLC controller, MP27622 4-channel digital isolator, and MPQ27811 4-channel digita...
DC FAST CHARGING SYSTEM: MAXIMIZING POWER DENSITY WITH AN LLC TRANSFORMER DRIVER
As the world strives for carbon neutrality, electric vehicles (EVs) are rapidly taking market share from internal combustion engine vehicles. However, one of the issues with electric vehicles is range anxiety, as customers are unsure of how long they will be able to drive without the car needing to be charged. To combat this, governments around the world are massively investing in charging infrast...
MPS'S ISOLATED MEDIUM- AND HIGH-POWER POWER SUPPLY PRODUCTS
Our lives are undergoing tremendous changes amidst the emergence of carbon neutrality, 5G, artificial intelligence (AI), and big data. The advent of the 5G era has transformed the design concepts of many power supply products, in that it has significantly increased the demand for medium- and high-power power supplies. Due to the increase in data traffic, communication frequency, and transmission ...
RECOGNITION AND ELIMINATION OF SUBHARMONIC OSCILLATIONS
DC/DC instability occurs due to a variety of factors, such as improper compensation parameters or insufficient layout. This article will discuss subharmonic oscillations, a form of instability that can be generated when current mode switching regulators have a continuous inductor current and a duty cycle exceeding 50%. These oscillations then create unstable power supplies. To learn about subharm...
MPS'S ISOLATED POWER SOLUTIONS PROMOTE CARBON NEUTRALITY
The revolution for a carbon-neutral era goes beyond an environmental commitment. With premiums on energy-saving solutions that reduce emissions, markets and individual companies are shifting their industrial and energy infrastructures to produce unique and environmentally conscious products. Across various power categories (e.g. photovoltaic and wind power generation, energy storage, battery manag...
