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...
