Why BLDC motors?
Electric motors are responsible for roughly 50% of the world’s total electrical energy consumption, according to the European Commission1. Improving motor efficiency not only reduces operational costs but also plays a vital role in lowering global CO₂ emissions. Among available motor te
Figure 1: A typical AES design includes power sources sharing a common high-voltage DC Link, an inverter for generating AC, and a system controller ensuring coordinated operation.

Solar- and wind-power-based home AESs (alternative energy systems) are becoming more popular among consumers.
To achieve the product lifetime that consumers demand and ensure user safety,

The intricacies of power design are not conversation pieces for electronic-product consumers. Nor should they be.
Consumers care about visible signs of power design in the product, including the
Figure 1: The principle of fuel gauging based on coulomb counting: The stored energy represents state of charge. A circuit measures the in- and out-flowing current.

For simplicity, you can imagine the battery as an energy storage device analogous to a fuel tank. However, measuring stored energy from an electrochemical device is far more complex than that comparison

Traditionally, PFC (power-factor-correction) controls present a purely resistive behavior with respect to the power line.
By means of multiplier or equivalent blocks, front-end converters draw

Li-ion technology with smaller, lighter-weight, and higher-power batteries is now replacing nickel-cadmium or lead-acid batteries in high-discharge-rate battery applications.
Meanwhile,
Over the past decade, controller-IC manufacturers have worked to reduce so-called vampire or stand-by power consumption. Organizations such as Energy Star in the US, Blue Angel in Germany, and CNIS
