Power Electronics
Electronic circuits that convert and control electrical power, including inverters, charge controllers, power optimizers, and EV charging circuits. The technology enabling the clean energy transition.
Why It Matters
Power electronics determine system efficiency and reliability. Silicon carbide (SiC) electronics are enabling smaller, more efficient inverters and EV chargers.
Related Terms
Inverter
A device that converts direct current (DC) electricity from solar panels into alternating current (AC) electricity used by your home.
Microinverter
A small inverter attached to each solar panel, allowing independent operation and optimization of each panel.
Power Optimizer
A DC-to-DC converter installed behind each solar panel that maximizes the output of individual panels before sending power to a central string inverter.
Charge Controller
A device that regulates the voltage and current from solar panels to a battery bank, preventing overcharging and deep discharge. Common types are PWM and MPPT.
