Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

The control circuit in Figure 1a allows you to manually adjust the power delivered to a load. By changing the setting of potentiometer R 3, you change the phase angle at which the thyristor (Q 3) ...

A new design solution implements analog-digital fusion control for power supplies serving small to medium industrial and consumer equipment operating at 30 W to 1 kW. It provides the same ...

The digital control of switching power supplies is firmly established in everything from EV onboard chargers (OBCs) to power-supply units (PSUs) in AI data centers to renewable-energy systems that ...

In many countries, plants have to fulfill specific requirements of the electrical grid (such as frequency control, dispatch control, automatic generation control (AGC), and so on) and are paid ...

Getting power to anything from lighting to video walls should not be an afterthought. Today’s digital endpoints have added new challenges, putting a spotlight on the need for proper power control and ...

Inductors are simple coils of wire, but they play a powerful role in electronics. This video explains how inductors store ...

Wherever circuits need protection against current overloads or short circuits, you’ll find circuit breakers. They range from fingernail-sized devices for semiconductor protection to truck-sized ...

The quest for higher power and greater efficiency in all power supplies never ends, especially when it comes to all heavy-duty converters. Some examples are power supplies used in data centers, ...
