Half-brick DC-DC converter

10 October 2018 Power Electronics / Power Management

SynQor introduced the new NQ40, non-isolated half-brick DC-DC converter – a buck/boost regulator which employs synchronous rectification technology to achieve extremely high conversion efficiency. The wide input voltage NiQor Brick family of converters can be used in traditional distributed power architecture systems or provide a regulated output voltage from a battery source or other variable voltage source.

The NQ40 has an input voltage range from 9 to 40 V. The output voltage range that can be achieved varies from 0 to 40 V d.c. at a maximum current of up to 55 A. The variable output voltage makes this device ideal for battery charging applications where a 12 V power source like a motor vehicle alternator can be used to charge deep-cycle batteries to their maximum charge.

This versatile device can be used in cascade to increase the available current to suit any application. The NQ40 half-brick form factor is small and has a high efficiency of up to 96% at full rated load current. Very little heatsinking is required for this device, saving on space and cost in a design, and mean time before failure has been demonstrated as more than 10 million hours.
