There are two main kinds of electric motors used in electric cars, though there are many variations on those themes. Tesla, for example, uses alternating current (AC) induction motors in the Model S but uses permanent-magnet direct current (DC) motors … Continue reading →

Switched mode supplies create smaller amplitude ripple waveforms than series regulators. Switched mode supplies dissipate less power in the control element than series regulators. Switched mode supplies provide better regulation at low power than series regulators. What is the advantage … Continue reading →

Though there many non-isolated SMPS exists, the three main types of non-isolated SMPS are Buck, Boost, and Buck-Boost SMPS. In these switch mode power supplies, no such device is used that can separate the switching circuit from that of output. … Continue reading →

Connect the positive terminal of the 12 volt power supply to one side of the resistor. Connect the other side of the resistor to the anode of the LED. Check the LED data sheet to identify the anode and cathode. … Continue reading →

A linear power supply is ideal for low-power applications which makes it equally unsuitable for high-power applications. In summary, the disadvantages of linear power supplies are higher heat loss, a larger size, and being less efficient in comparison to the … Continue reading →

If your laptop won’t power up, a faulty power supply, failed hardware, or a malfunctioning screen could be to blame [1]. In many cases, you may be able to resolve the problem yourself by ordering replacement parts or adjusting your … Continue reading →

The Basics of a Switch Mode Transformer When the power is turned on, the AC main power gets filtered through a capacitor, which converts the AC voltage into unregulated DC voltage. The transformer then uses a regulator to convert the … Continue reading →

You give up some niceties for the lower price, of course: this camera isn’t weather sealed and its electronic viewfinder isn’t quite as immersive or sharp as the X-T3’s. But those trade-offs are fairly standard at this price. Are Fujifilm … Continue reading →
