Meaning of P & Z
AC/DC lighting applications include signage, street lights, GU10, par lights, A19 bulbs, recessed downlighting, T8 tube lighting, and troffer lights. Any LED lighting setup must offer high energy efficiency and peak reliability to extend the lifetime of the light. Because LEDs are quickly becoming the leading lighting technology in office, industrial, and home-based situations, there is now a grea...
SMART PLUG REFERENCE DESIGN - MP161 NON-ISOLATED BUCK REGULATOR WITH ESP8266
Nowadays everything is connected. So why not also connect the wall plugs? MPS presents a reference design with the MP161 part that will allow customers to join the IoT market. This is a two boards product, one for the DC/DC converter and the relay and the other for the Wi-Fi module. The configuration is designed to fit into a wall-plug. IoT non-isolated designs This refer...
HIGH-POWER PFC: TOTEM-POLE PFC VS. INTERLEAVED BOOST PFC
Modern power supply designs require advanced power factor correction (PFC) circuitry to meet strict power factor (PF) standards while maintaining high efficiency and low cost. Interleaved boost PFC is the most commonly used PFC topology, but the advent of wide-bandgap semiconductors has enabled the implementation of bridgeless topologies like totem-pole PFC. This video explores the composition and...
LITHIUM-ION BATTERY CHARGER IC BASED MAXIMUM POWER POINT TRACKING SYSTEM
In an era characterized by the internet of things (IoT), more connectivity means more outdoor devices are now battery-powered and constantly communicating. In particular, an increasing number of outdoor devices are being powered through solar panels. The charger should be suitable for maximum power point tracking (MPPT) in outdoor designs with a solar panel. This article illustrates design tips fo...
POWER FACTOR CORRECTION
Power factor is defined as the ratio of energy a device is capable of transmitting to the output versus the total amount of energy it takes from the input power source. It is a key figure of merit for the design of electrical devices, especially due to the regulations put in place by countries and international organizations like the EU, which define the minimum power factor or maximum level of ha...
BATTERY CHARGER WITH MPPT REFERENCE DESIGN
APEC 2020 HR121X DEMO
AC/DC power supply designs must meet strict performance and size requirements. This video explores the HR121x family of full digital PFC + LLC combo controllers from MPS. PFC + LLC Controllers HR1210
TOTAL INTEGRATED POWER SOLUTION FOR SMART LIGHTING
Smart lighting is considered to be the new frontier of the global lighting industry, as the trend of smart homes, Internet of Things (IoT), and a connected world are the main driving factors in global electronics growth. In terms of major applications of the smart lighting concept, the industry is currently more focused on light intensity dimming, lighting color temperature adjustment, ambient sen...
CAPACITIVE ISOLATION: A FUNDAMENTAL BUILDING BLOCK IN FUTURE AC/DC POWER CONVERSION
Capacitive isolation is a mature solution developed over the past decade to replace optocouplers in signal isolators, isolated gate drivers, isolated transceivers, and other applications1. However, the potential to use capacitive isolation to replace optocouplers in offline adaptors is often neglected. This articles explains why capacitive isolation can be a fundamental building block in future AC...
