ECT 300 Perpetuum

Ultra Low Power DC/DC Converter

for Thermal Energy Harvester

ECT 300 extends EnOceans developer kit

EDK 300 by thermal energy harvesting

technology. Wireless sensor and even ac-

tuators can be operated by a few Kelvin

temperature difference.

EnOceans energy harvester is based on a revolu-

tionary ultra low voltage DC/DC converter which

starts operation at already 20mV

. For compari-

son: the leading conventional DC/DC converters

need at least 500m-600V to start operation - a

factor of 25x more!

The output power is in the range from W to mW

at 3.4V and depends on the actual temperature

difference at the Peltier element. It is designed

and optimized for use with EnOcean radio tech-

nology in sensors and actuators. A typical

thermo-driven sensor consists of a sensor ele-

ment, a small Peltier element, the ultra low volt-

age DC/DC converter and an EnOcean STM radio

module.

Example calculation for accumulated energy from

ECT 300-2 in combination with Peltier/Seebeck

(TEC2L-15-15-15-5.6) element and heat sink

(SK426).

10癈 average temperature difference @ peltier:

0.5mW x 24h x 365d = 4,380mAh per year

20癈 average temperature difference @ peltier:

1.4mW x 24h x 365d = 12,264mAh per year
