Racking in or out a power circuit breaker is simple, right? Although this task sounds pretty straightforward in theory, that’s not always the case. In fact, during years of field work related to ...

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 ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system battery drops to lower voltages. They make sense when a single-stage ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

The Machine Primary Control Elements (MPCE) 1 and 2 are typically a relay with force guided contacts. When a safety interlock, light curtain, or e-stop switch opens a circuit, the MPCE NO contacts ...

A new type of device provides designers of automated installations for North America with performance, cost, and safety benefits. Industrial machinery and equipment system designs typically rely on ...

One simulates up to 50× faster than the other, and both will give you comparable accuracy. Which engine would you choose for your power supply circuit? Sounds like a trick question, but it isn’t.
