Precise motor control has gained greater significance as electrification takes over the automotive industry. Whether for electronic power steering, electronic stability control, automatic braking ...

Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...

Today, compressor overheating is one of the HVACR industry’s most serious field problems. Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused ...

Having both 3-phase and single-phase loads can be challenging when trying to balance the voltages at a facility. It’s possible that during a facilities operation, one phase can be lightly loaded ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Murata Power Solutions announced the ACM3P series of low profile 3-phase AC digital ammeters suitable for front panel mounting. Capable of high precision measurement to within 0.1 A and display of ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

At APEC 2026, Efficient Power Conversion (EPC), is introducing the EPC91121 motor drive inverter evaluation board, built around the Gen-7 EPC2366 40 V eGaN power transistor and sh ...
