Power MOSFET Design Equations
here are only few power MOSFET design equations to take note when doing design involving this electronic part. You may try deriving these equations if you want a better understanding on how these formulated. These are also given in application notes and some technical blogs but maybe in different form but will result to the same calculation results.
READInverter Aircon Can and Cannot Save Money
Advertisers said that end user can save up to 50% of their electric bill compared to the conventional or non-inverter aircon. Is this true? Well, let us talk about it, so keep reading. I actually say that inverter aircon can and cannot save money. Inverter aircon is a new technology; actually, not anymore very new as of this writing but there is no other technology so far newer than this in air conditioning world.
READHow to Know if a Transistor Defective
Transistor is an active electronic part. An active electronic part is something can perform amplifications or signal processing. Transistors are basic elements on power amplifiers, audio amplifiers, switching converters, power supplies and so on. A transistor term is somewhat generic. It could be a BJT, MOSFET of JFET. But for common people (electronic hobbyist), it is commonly referring to a
READHow to Know if a Relay Defective
Relay is an electromechanical part though nowadays there is already a so-called solid-state relay. An electromechanical means a combination of electrical and mechanical actions or functions. For hobbyist, it is important how to know if a relay defective. But before going to that, let us discuss the basics of a relay for better understanding. As mentioned above, a relay is
READPurpose of Power Factor Correction
The purpose of power factor correction is to condition the line current. To condition simply means making the line current smooth by filtering the spikes and any irregularities in the waveform. A smoother line current will have low power loss. Some images below are showing a line current with a very bad power factor. The yellow and pink waveforms are
READHow Electric Meter Works
How electric meter works? Electric meter records the consumer energy consumption. Energy is the product of power and time. You may be already heard about the term “kilowatt-hour”. This is the unit of energy measured by the electric meters. The power considered is the real or true power that is consumed by the users. There are two common types of
READHow Power Bank Works – Principles and Concepts Explained
Cell phones, tabs and other gadgets nowadays are having so many applications which correspond to higher energy consumption that the battery charge cannot last long. Thanks to power banks; we can use our phones and gadgets in the whole day without the need of an AC power. Let us uncover how power bank works. Types of power bank Non-portable Non-portable
READWireless Charger Design Principle Concept Explained
The future of charging is through wireless charging. Wireless charging is different from the conventional way of charging phones, tabs and gadgets. It is not using any cable or wires between the charger and the device to be charged. It seems complicated but here we are going to hack how it works and how wireless charger design principle differ with
READSwitch Mode Power Supply Explained with Common Topologies
For small power applications like on board power sources, linear power supply is often used due to its simplicity and low cost. However, when the need for high power density designs arises, linear power supply simply disappears in the picture. It is because linear power supply is very less efficient. Switch mode power supply comes in place. Switch mode power
