Dc-Dc converters ideal for renewable energy applications

CUI’s Power Group has announced a new line of dc-dc converters ranging from 5 W to 40 W. The AE series, available in board mount, chassis mount, and DIN rail mount configurations, offers power ratings of 5 W, 10 W, 15 W and 40 W with input voltages up to 1500 Vdc and input ratio ranges up to 10:1.

Designed for reliable operation in renewable energy applications such as solar power equipment, wind turbines, and electric charging stations, the new models feature 5600 Vdc input to output isolation and a wide operating temperature range up to -40 to +70°C at full load. The series is also rated to operate at up to 5000 meters, allowing it to support remote, high altitude installations.

These new isolated dc-dc converters are housed in fully encapsulated packages for use in harsh environments with measurements beginning at 2.75 x 1.89 x 0.93 inches (70 x 48 x 23.50 mm). Output voltage options of 5, 9, 12, 15, and 24 Vdc are available, depending on the series, including efficiency ratings up to 84%. Protections for over voltage and over current as well as continuous short circuit with automatic recovery come as standard.

The AE series also carries EN 62109 safety approvals and complies with CISPR22/EN55022 Class A limits for conducted and radiated emissions, while the AE-UW series is designed to meet an additional UL 1741 safety standard.

GaN’s Ground-Floor Opportunity
The electronics industry has a major role to play in helping to save energy, by enabling better equipment and new ways of working and living that that are more efficient and environmentally friendly. Maintaining the pace of technological progress is key, but improvements become both smaller and harder to achieve as each technology matures. We can see this trend in the development of power semiconductors, as device designers seek more complex and expensive ways to reduce switching energy and RDS(ON) against silicon’s natural limitations.
