IGBT rectifier UPS systems from ProstarM are enabled with a high input power factor (>0.99) and low THDi (≤ 3%) apart from having online double conversion technology and DSP control. Over the past decade, ProstarM has emerged as a leading manufacturer of a wide range of industrial UPS systems including IGBT rectifier UPS systems which have a strong mixed load capacity and high overload capacity.

Definition and working of IGBT

Insulted gate bipolar transistors (IGBT) are power semiconductor devises with 3 terminals. They operate as an electronic switch. In IGBT rectifier UPS systems, they maintain frequency output, and bringing high efficiency, quick switching and stable power supply. Multiple IGBT rectifiers can be used in a UPS, depending on the size of the IGBT rectifier UPS system. The larger the size of the IGBT rectifier UPS, the more IGBT devices it incorporates. When deployed in IGBT rectifier UPS system, the service life of the IGBT devices depends on the load supported by the IGBT rectifier UPS and the working environment of the UPS system.

UPS systems often use relays and thyristors, but the relays have a conversion time and the life of the electromechanical device creates an issue. With thyristors, the problem is that they are complicated to control and can generate circulating currents of up to 10ms. IGBT rectifier UPS systems eliminate these problems. UPS with IGBT are simple to control and much more efficient than thyristors. Similarly, PFC circuits also use IGBT as a power device. When IGBT is used in a PFC rectifier, it improves the efficiency of the system. IGBT rectifier is also used in high frequency online UPS as the power device of the invertor part. Another major advantage of IGBT rectifier UPS system is that IGBT device has a high voltage capability. It is easy to drive and has zero gate drive current. These features make IGBT rectifier UPS the perfect fit for high-voltage applications.
