Offline flyback IC incorporates zero-voltage switching topology
Power Integrations announced the release of theInnoSwitch5-Pro family of high-efficiency, programmable flyback switcher ICs. The single-chip switcher achieves over 95 percent efficiency with a novel secondary-side control scheme which achieves zero-voltage switching (ZVS) without a dedicated and costly additional high voltage switch. The new IC, which features a 750 V or a 900 V PowiGaN primary […]
TTape: A simple way to monitor Li-ion battery-pack temperature
A set of temperature-triggered switches alerts you to hot batteries. Li-ion batteries can get hot, which can cause failures or worse in the products they power. Thus, it’s important to monitor their temperature and act before damage occurs. You can monitor temperature with a set of thermocouples, scan them, and write software to produce an […]
IGBT modules for applications operating at 200 to 3300 V C now available in 20 and 3-level topologies
The paradigm shift towards offloading complexity to suppliers and adopting smaller IGBT modules is evident in various applications. In response to the global push for downsizing and integration, Infineon Technologies AG introduces the 4.5 kV XHP 3 IGBT modules that will fundamentally change the landscape for medium voltage drives (MVD) and transportation applications operating at […]
New GaN FETs for soft switching applications
Central Semiconductor announces the introduction of several new Gallium Nitride (GaN) FETs.
