Generating really high voltages without a Tesla coil
There are many ways to create high-voltages and pulses; the Marx generator is a simple one in concept and practice. Low-voltage designs with rails in the single digits get a lot of attention these days for reasons I don’t need to detail to this audience. Still, there are many situations where rails at hundreds of […]
How to commutate BLDC motors
BLDC motors are highly efficient and growing in use in various applications such as robotics, electric vehicles, and drones. However, to extract optimal performance from these motors, the correct commutation technique is crucial. Commutation is the process of changing the direction of the current in the motor windings, which generates torque and rotates the motor. […]
What to look for in surge protection for power supplies
By Ron Stull, CUI, Inc. Any mains-powered electrical device is vulnerable to voltage surge. These completely unpredictable events can take many forms: from modest power spikes during normal operation to massive power surges caused by an external lightning strike. To prevent damage and downtime, electrical equipment and circuits need to be provided with adequate surge […]
Supercapacitor modules available for 9, 18, and 30 V outputs
A new line of standard supercapacitor modules has been announced by Cornell Dubilier (CDE). The DSM Series responds to the need for supercapacitor storage capabilities at higher voltages than what single components can provide. The new modules are offered in packs with 3, 6, or 10 cells in series for 9V, 18V, and 30V outputs. Capacitance […]
