The AWG circuit utilizes a cutting-edge synchronous buck topology, operating at an impressive switching frequency of 200kHz even under full load. What sets this converter apart is its innovative hysteretic control topology, which dynamically adjusts the switching frequency based on changes in the output load. This intelligent control mechanism ensures that the input voltage is optimally available to drive the rise time of the output current, resulting in unparalleled performance and efficiency.
In addition, the AWG boasts a remarkable feature - a high-frequency switched-mode post regulator that offers the unique ability to reverse the polarity of the delivered output. With the four switches expertly modulated, the output polarity can be precisely set according to the commands of the external host system.
With its flexibility in packaging options and the ability to connect converter blocks in parallel, the AWG circuit enables support for higher output power. For instance, by connecting eight of these assemblies in parallel, a semiconductor laser application can achieve astonishing slew rates of 8,000A/ms. Additionally, the high current control bandwidth and the output capacitor of less than 100uF (providing ~3uF/A at 30A) further contribute to the AWG's exceptional performance.
Astrodyne TDI's latest breakthrough innovation, the AWG, revolutionizes AC to pulsed DC output power systems. With its ability to provide output current slew rates exceeding 1,000A/ms, it not only ensures exceptional performance but also effectively manages component reliability concerns arising from thermal fatigue and safe operating conditions.
