CIPOS Mini IPMs from Infineon integrate power factor correction
Infineon Technologies introduces the CIPOS Mini intelligent power module (IPM) featuring power factor correction (PFC). The CIPOS Mini IPM combines a single switch boost PFC stage and a three-phase inverter in one package.
According to Infineon, with the PFC integrated into the inverter module, the integrated CIPOS Mini IPM can help to reduce system size, allow room on the printed circuit board (PCB) for more components, and reduce the bill of materials. The CIPOS Mini is designed to control induction motors and permanent magnet synchronous motors with single-phase PFC in variable speed drives. These are typically found in applications like air conditioning and low-power motor drives of up to 2kW power capability, says Infineon.
The PFC IGBT of the CIPOS Mini IPM uses an external driver circuit allowing customers to enhance switching performance. The IPM features a Trenchstop insulated-gate bipolar transistor (IGBT) combined with an optimised silicon on isolator (SoI) gate driver for electrical performance.
CIPOS Mini PFC integrated IPMs are available in inverter current ratings of four, six, 10 and 15A. Designers can choose between PFC switching frequency of 20 or 40kHz. The package is especially designed for power applications which need good thermal conduction and electrical isolation, says Infineon. It also allows EMI-safe control and delivers overload protection.
Depending on power rating, CIPOS Mini IPMs are available either in DCB or fullpack. Both versions feature over-current protection, along with an integrated under-voltage lockout function, and built-in temperature monitor. This provides for a high level of protection and fail-safe operation, claims Infineon. Additionally, the integrated bootstrap diodes for the high-side drive function simplify the system design while reducing overall system cost.
The CIPOS Mini PFC integrated IPMs will be available in volume production (10 and 15A devices) in June 2017. The four and 6.0A versions will be available during Q3.
The CIPOS Mini IPM will be showcased at the Infineon booth (Hall 9 – 412) at PCIM Europe 2017 (16 – 18 May) in Nuremberg, Germany.
