The ground is not just ground! At least not in hospitals, medical, and dental practices
This technical article analyzes the safety requirements against indirect contact employed in particularly special medical locations (e.g., hospitals, medical, and dental practices, etc.), where environmental conditions may increase the risk of indirect contact and therefore the electroshock, precisely microshock. Generally… Read more

Yup, it’s the motor drive that makes systems in motion all around us
On the outset, it may be due to wheels as in the case of an automobile. What actually drives these movements, though, are motors. Additionally, many household appliances such refrigerators, air-conditioners, ventilation fans, washers, driers and so many others all… Read more

Never underestimate electrostatic discharge (ESD) while working with data networking equipment
Let’s start with basics you probably already know, but nevertheless. It’s important to explain the basics first. Electrostatic Discharge (or ESD) refers to the transfer of electrostatic charge between bodies at varied voltages that is caused by direct contact or… Read more

8 tips to avoid ground loops when dealing with signal level circuits
General recommendation is to properly design and implement the facility’s grounding system to avoid unwanted involvement of ground loops with the operation of the equipment. This kind of approach can also eliminate the need to consider equipment modifications and to… Read more

Few advice for improving integrity of protective conductor
Most modern electronic equipment uses switched mode power supplies (SMPS) which draw pulses of current from the mains supply rather than a continuous sinusoidal current. The fast rise time edges of the current waveform contain high frequencies that can cause serious radio frequency… Read more

Should We Blame Supplier For Voltage Dips and Transients?
Voltage dips and transients are usually blamed on the supplier, but this is often unfair. There are many potential on-site causes; for example, starting of heavy loads may cause voltage dips and switching of inductive loads will generate transients. Let’s… Read more

Super Capacitors – Different Than Others (part 1)
Capacitors store electric charge. Because the charge is stored physically, with no chemical or phase changes taking place, the process is highly reversible and the discharge-charge cycle can be repeated over and over again, virtually without limit. Electrochemical capacitors (ECs) variously… Read more

Difference between step-up transformer and voltage amplifier
A step up transformer basically increases the magnitude of primary applied voltage that is increases the amplitude of voltage wave form. A voltage amplifier does exactly the same. Than a very strange but thinkable question comes what is the difference… Read more

Power Semiconductor Device – MOSFET
Power MOSFETs are marketed by different manufacturers with differences in internal geometry and with different names such as MegaMOS, HEXFET, SIPMOS, and TMOS. They have unique features that make them potentially attractive for switching applications. They are essentially voltage-driven rather… Read more
