Flyback transformer packaging eliminates need for flying leads
The new MID-OLRM extended rail RM8 transformer series for offline applications from Wurth Electronics Midcom is now available. “For the past 30 years, the RM packages have required flying leads to meet reinforced insulation and creepage and clearance distances. We decided to change this by adding an extended rail to the existing RM8 package; eliminating […]
Offline transformers for LLC resonant half-bridge topology
Wurth Electronics Midcom is proud to announce the release of MID-LLCEPC; a new series of offline transformers using LLC Resonant Half-Bridge topology. With the low switching losses of the LLC topology, the MID-LLCEPC series yields very good efficiency, which makes the topology attractive with higher power levels. “Our package used for this series was designed […]
Low-profile gate drive transformers feature 1.5 kV isolation
The new MID-GDT transformer series is now available from Wurth Electronics Midcom. These low profile gate drive transformers are surface mount with a maximum height of 5.38mm, and operate with a voltage-time product of at least 70 Vµs on secondary windings. These pick-and-placeable transformers feature 1500V isolation, and have an operating temperature of -40° to […]
Modeling losses in magnetic components
Traditional ways of calculating the loss in inductors and other kinds of magnetic components have well-chronicled short comings that suppliers are beginning to address. RANJITH BRAMANPALLI | WURTH ELECTRONIK IN A SWITCH MODE POWER SUPPLY (SMPS) most of the power losses take the form of switching and magnetic losses. Magnetic loss stems from the core […]
Powerline chokes withstand 760 V
A rated voltage three times higher than the voltage of the existing family of WE-CMB chokes – this is the outstanding feature of the current-compensated power line chokes of the WE-CMB HV series offered by Würth Elektronik eiSos. Europe’s leading supplier of electronic and electromechanical components has designed these new common mode chokes for network […]
