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
