Edison vs Tesla -DC Power vs AC Power- There are many machines that use electricity as a power source, such as electronic devices and home appliances around us. And in the case of Japan, most of them may be operatin[...] Installation of DC Power Supply and remote sensing correctly and safely Contains DC power supply know-how and how-to-use! Matsusada Precision is the leader in power supply manufacturing PROPER INSTALLATION OF POWER SUPPLY CONNECTION OF LOAD[...] Digital Measurement and Resolution -Basics of IoT- In the last column, we introduced power semiconductors and improved their performance. We also mentioned that improving performance requires numerical measurements from several[...] Types of Power Semiconductors -Reliability and Performance Test We introduced how to make a DC power supply from a grid connection and an AC power supply until the last column. These conversions are basically done by circuits, and they are [...] Method of Generating Direct Current (DC) Power In general, electronic devices operate at direct current. This is common to home appliances such as smartphones, Computers, TVs, refrigerators, and air conditioners, as well as [...] Electric grid (power system interconnection) to Learn from Scratch Do you know that there was a "switch" until about the 1980s in the case that you buy home appliances, especially when you connect lighting equipment to an outlet in Japan? Thi[...] How to Use Bidirectional Power Supply First, we explain what a bidirectional power supply means. A converter that can convert DC and AC bidirectionally to any power system is called a bidirectional power supply. It [...] Electric Vehicle Motors: Battery and Supply Voltage With the support of the government, many European countries, the United States, and China are advancing the transition from conventional automobiles to electric vehicles. In Jap[...] Electric Double-Layer Capacitors are Optimal for Leveling Power Unlike a normal capacitor, a double-layer capacitor has a large electric capacity because the electric double-layer, that is a layer with the opposite polarity to the electrode [...] Battery Types and Characteristics of Charge Control Rechargeable batteries have various features depending on their type. At first, we introduce battery type. LiB Lithium-ion battery is used in a variety of applications, from s[...] Preceding 10 items 1 2 3 4 5 6 7 8 9 10 11 Next 10 items
