Hybrid-Regulated-Ratio Quarter-Brick Delivers Up To 600 W For Advanced Telecom

May 28, 2014
Ericsson leveraged its hybrid-regulated-ratio (HRR) topology to create the third version of its high-power-density quarter-brick power module.

Ericsson leveraged its hybrid-regulated-ratio (HRR) topology to create the third version of its high-power-density quarter-brick power module. As a result, the PKM4613NH offers power up to 600 W across a 36- to 75-V input voltage range at an operating temperature ranging from ‒30 to +90°C. HRR technology, which combines voltage and duty-cycle regulation, enables high-power conversion operation over such a wide input voltage range, while minimizing power losses. The end result is an efficiency power conversion of up to 96%. The dc-dc converter matches a variety of system bus voltages powered by multi-cell batteries or rectifiers commonly used in the information and communication technologies (ICT) industry. In addition, 580-W power remains available when reaching the low limit of the 40.5-V service voltage. Tightly regulated output voltage over the entire operational range stabilizes the voltage for the target load if there’s line disturbance. Supply currents run as high as 50 A. Power is delivered through four power-pins to reduce power losses and improve thermal conduction across the motherboard. Input/output isolation is 2250 V dc.
