Energy harvesting assisted self-powered electronics systems are picking up in momentum, due to the fast growing market of the Internet of Things (IoT) sensor networks. Environmental energy harvesting has attracted much attention as a possible power source for remote electronic devices and implanted/embedded electronics..
A 37μW-input Boost Converter with 82% Efficiency for Thermoelectric Energy Harvesting
A high efficiency low power boost converter for thermoelectric energy harvesting is presented in this paper. The converter is implemented in a 180-nm bulk CMOS technology. Due to the proposed adaptive input ripple maximum power point tracking (AIR MPPT) method, the end-to-end system efficiency (ηE-E) at low input powe..
PFM Boost Converting Charger with Input Ripple Regulation for Thermal Energy Harvesting MPPT
With small input capacitor (CIN) of the charger for Internet of Everything applications, input ripple of the charger can be huge, which degrades harvesting system power conversion efficiency (ηSYSTEM). In proposed work, the input ripple of the charger is regulated as optimum value that makes ηSYSTEM maximum. 1μF CIN..
100V Boost Converter
This IP is a PWM Boost DC-DC converter with maximum 100V output voltage that operates from an battery voltage as low as 3.5V.
The pulse width and frequency of PWM is controllable by logic signal.
This is useful for DC-DC converters operating from high voltage applications such as piezo haptic driver.
