Power Integrations introduced the 2SC0115T2A0-12 dual-channel gate driver core for inverters and converters from 90kW to 500kW.
The new driver core utilizes SCALET-2 + integrated circuit and isolated transformer technology for DC-DC power supply and switching signal transmission, thereby eliminating the need for optocouplers, thereby improving system reliability and performance. The operating voltage of the reinforced electrically insulated target system of the driver core is 900 V, which is the typical voltage of a 1200 V IGBT module and meets the PD2 and OV II requirements of IEC 60664-1 and IEC 61800-5-1. The 2SC0115TA0-12 gate driver core supports modules up to 2400A and switching frequencies up to 50kHz.
The 2SC0115TA0-12 gate driver core measures 53.2mm x 31mm and measures only 13mm, making it the most compact industrial unit in its class. Compared with competitors' products, the highly integrated SCALE-2 + chipset uses about 85% fewer components and includes short circuit protection provided by Vce-sat monitoring and independent power supply voltage monitoring on the primary and secondary sides. The new gate driver core includes soft shutdown (SSD) protection for applications with low stray inductance. For more demanding environments, the 2SC0115TA0-12 supports a fully advanced active clamp (AAC) to control the voltage overshoot of the IGBT during turn-off.
Each of the two output channels is electrically isolated from the primary side and the other secondary channel. Each channel can provide ± 15A output current and 1.2W drive power with a gate voltage swing of + 15V to -6V. The company said that regardless of the output power level, the turn-on voltage will be adjusted to maintain a stable 15V.
Michael Hornkamp, ??senior director of high-power product marketing at Power Integrations, said: "The 2SC0115TA0-12 gate driver core is an ideal platform for 600V and 1200V IGBT modules in medium power applications such as general-purpose drivers, UPS, photovoltaic inverters and medical applications, especially These are the applications that are challenging and require fast switching.
