Trams, subway trains and buses experience a high number of acceleration and deceleration cycles on a daily basis. As well as a changing electric and thermal load, the power electronics systems are also subject to vibrations. Power Integrations has developed a range of IGBT-drivers specifically to suit this demanding application. The plug-and-play drivers 1SP0635 and 1SP0335 allow a fully scaleable design which can easily follow different voltages or power ratings. Especially for the requirements of an extended temperature range down to -55°C Power Integrations offers the driver core 2SC0535 for voltages up to 3300V.
