ESBT for SMPS designs

1 October 2008 Power Electronics / Power Management

STMicroelectronics has introduced a new ESBT (emitter-switched bipolar transistor) power switch, which enables engineers to improve efficiency, cost, component count and size in auxiliary switched-mode power supplies (SMPS) for single- and three-phase applications.

The STC03DE220HV is the first in a new family of ESBTs rated for 2200 V breakdown voltage, allowing designers to use a single-switch flyback topology in universal-input converters operating from 90 to 690 V a.c.

Operating efficiently at 150 kHz maximum switching frequency and 3 A maximum rated current, the STC03DE220HV can be used in a wide range of auxiliary SMPS applications including industrial utility metering, inverter drives for induction motors, welding equipment and uninterruptible power supplies.

Using ESBT technology, the STC03DE220HV betters standard bipolar transistors as well as high-voltage MOSFETs by combining low on-state losses with the traditional MOSFET advantages of high switching frequency and easy gate-driver design. The STC03DE220HV achieves an equivalent on-resistance of 0,33 Ω, from the collector to source.
