Basic Circuit Operation
We offer an intelligent microcontroller, development system for front-end evaluation and a full range of downloadable documents to simplify the design process. Pulsiv OSMIUM provides a scalable platform for engineers to reduce size, improve energy consumption and optimise cost when designing a power supply for virtually any mains powered or battery charging based application.
Consumer Devices
Leading electronics brands are constantly seeking ways to create a competitive advantage, often using technology innovation as a key differentiator. Pulsiv solutions deliver significant improvements in power density, efficiency and size without compromising on cost. We are actively engaged with consumer device manufacturers to demonstrate how our technology can achieve their goals, meet strict industry regulations and reduce overall energy consumption.
LED Lighting
With changing regulations and energy prices at an all-time high, the LED lighting sector is expected to grow significantly over the next 10 years. Our technology can be used by lighting manufacturers to design more sustainable, cost effective and energy efficient products. As the first company in the world to completely eliminate inrush current in LED drivers, large scale lighting projects become less complex, lower cost and faster to install.
Industrial Power Supplies
Commercial off the shelf power supply manufacturers continue to improve power density, efficiency and reliability for a diverse range of applications from factory automation to medical devices. Our flexible technology provides a new platform to develop an entire portfolio of highly efficient, ultra-compact and low cost power supplies. Additional features include; extending the range of flyback technology (to 350W), automatic x-cap discharge and the complete elimination of inrush current to simplify product design.
Power Adapters
Power adapters are commonly used in household appliances that operate or charge from a wall socket. Regulations around the world are constantly evolving to promote standardisation, improve safety and reduce power consumption. Pulsiv offers leading technology to address these challenges by enabling the use of conventional flyback designs to improve power density, efficiency and size compared to higher cost alternatives. Our solutions can also be optimised for USB-C adapters which will become mandatory in Europe following amendments to the EU Radio Equipment Directive aimed at reducing electronic waste.
Battery Chargers
Many applications now use batteries as their main source of power. While innovation in battery technology offers the possibility to improve storage capacity and charge rates, high performance power electronics are required to unlock the full potential. We’ve made it possible to use conventional flyback designs up to 350W with a universal input voltage range to charge the most advanced batteries. Our solutions contribute to improving efficiency, reducing size and optimising cost in the development of ultra-fast battery chargers.
Solar Technology
Solar has become a popular choice for generating clean energy and Pulsiv provides enabling technology to ensure that every watt of free power is made available to the customer. Pulsiv HORIZON designs extract previously unexploited solar energy, efficiently produce AC or high-voltage DC electricity and can be configured to perfectly match panel capability. Making Pulsiv HORIZON available to a broad ecosystem can increase total capacity, improve the economics of solar power generation and accelerate the global transition towards renewable energy.
Delivering a unique combination of benefits
Unrivalled Efficiency Profile From Low Power to Full Load
A Pulsiv OSMIUM front-end solution exceeds the Energy Star VI standard by up to 20%. This enables the use of flyback technology at higher power levels, simplifies the design process, and can improve overall energy consumption.
Replace LLC Designs with Flyback Technology
Conventional LLC designs can now be replaced with more cost effective flyback solutions when paired with Pulsiv OSMIUM technology. Our unique approach can extend the range of efficient flyback designs (180W single-switch and 350W interleaved with universal input) to reduce losses and improve overall energy consumption.
Improved Thermal Performance for Higher Reliability
In a Pulsiv OSMIUM design, critical components operate at temperatures far lower than conventional power supplies. This reduces component failures and extends expected life time, even under convection cooling.
Inrush Current Eliminated
By regulating the flow of mains to the charging capacitor, Pulsiv has become the first company in the world to completely eliminate inrush current. For manufacturers of Industrial Power Supplies/LED drivers, system design, installation and cost is significantly improved.
Integrated Features
For complete design flexibility, Pulsiv OSMIUM offers a variety of integrated features which can be used according to the needs of the application and the desired output power.
STANDARD FEATURES INCLUDED:
X-Cap Discharge - Pulsiv’s microcontroller, when used with a half-active bridge, offers the signals to discharge the x-capacitor automatically. Currently, x-cap discharge is only possible by using ana external silicon chip adding cost and space, or by using resistor which whilst low cost, continounosly dissipates heat resulting in a less efficient solution.
AUX Output Control - Signals are provided to produce an auxiliary power source which is independent from the main power supply. This standard feature can be used without the need for a separate controller which typically requires additional space, cost and design time.
Grid Failure Detection - When the grid supply falls below SOV, a signal is provided to give the earliest possible warning so that any necessary action can be taken in dow nstream systems. This is particularly useful in safety critical applications or where a controlled shut down is required.
Power Consumption Indicator - A signal is provided as standard that switches at a frequency which is directly proportional to the output power. This can be used to indicate or log real time power consumption w ithout the need for additional components that are traditionally used to support this feature.
Selectable Max HVDC Output - Providing the ability to select the voltage rating of the storage capacitor, allows engineers to optimise the capacitor selection for cost or performance. This flexibility enables engineers to configure the design according to the needs of their application by choosing between 160V or 200V capacitors.
OPTIONAL FEATURES
Active Bridge Control - Using an active bridge in a switch mode power supply design is a recognised method to improve efficiency and reduce losses when compared to a traditional bridge rectifier solution. Signals are provided to manage and support the additional components.
Configurable Hold Up - Hold up provides energy storage for a system to continue operating for a period of time after the input supply is lost or removed. Once engineers have defined the required hold up time, they can configure the necessary components to meet the needs of their application.
For more information on any of these features, please refer to the PSV-AD-xx datasheets or contactus directly. - Aby uzyskać więcej informacji na temat którejkolwiek z tych funkcji, zapoznaj się z arkuszami danych PSV-AD-xx lub skontaktuj się bezpośrednio z nami.
Scalable Platform
The Pulsiv OSMIUM microcontroller does not directly determine the output power. Changing only 3 key components (Inductor, Mosfet & Capacitor), ensures it can be used across a family of products.
Seamless System Integration
Circuit configurations combine a Pulsiv OSMIUM microcontroller and various supporting components to deliver a complete AC-DC front-end design. Full reference designs combine a front-end circuit configuration with a pre-selected DC-DC converter to deliver an end-to-end solution that meets the relevant EMC/FCC regulations.
