IXYS Corporation (NASDAQ: IXYS), a leader in power semiconductors and integrated circuit technologies for energy efficient products used in power conversion and motor control applications, announced today the release of its latest addition to the ISOPLUS TM Surface Mount Power Device (SMPD) range which successfully reduces the amount of discrete devices for designers that need to apply Insulated Gate Bipolar Transistors (IGBT), thyristor and fast diode technologies in one circuit.
The patented SMPD Module platform has successfully improved reliability and reduced board size by offering surface mount solutions for systems up to 15kW. Using IXYS’ proprietary DCB isolated substrates the SMPD Module flexibility provides a platform for mixed technology and multiple die content, e.g., thyristor, IGBT, MOSFET and diode in boost, buck, parallel, half bridge, full and three phase bridges or two switches side by side topologies.
“Incorporating our thyristors with our IGBT’s has been a natural extension of our depth in power semiconductor technologies. The thyristors have been the highest power density switches for the industry and are relatively easy to drive as high side switches in bridge configuration. They conduct higher currents with higher efficiencies than FETs and IGBTs, thus a combination with FETs or IGBTs creates almost an ideal switch, where the high-side-high currents, are conducted by the thyristors, and high speed switching is done with the low side IGBTs in this product,” commented Dr. Nathan Zommer, CEO of IXYS Corporation. “More combinations of these technologies are possible, and will be introduced to our customers' needs as applications power devices (ASPD).”
Integration of the thyristor into a half bridge with an IGBT provides a one-stop solution for power designers needing to operate a low frequency bridge (thyristor) with higher frequency modulation (IGBT). The example of the IXA20PT1200LB is a 20A, 1200V SMPD surface mountable module which contains a thyristor at the high side and IGBT technology on the low side of a half bridge circuit allowing an energy efficient solution for applications such as current source micro-inverter, UPSs, power supplies, motor drives and medical applications.
