Buck Converter Design Tutorial
Buck Converter Basic Function Before going to buck converter design tutorial, we will discuss first how buck converter works in order to fully understand the following tutorial. A buck converter is a switching converter with a voltage output lower than voltage input. It is also called as a step-down switching converter A buck converter has only four main parts. They

How to Know a Defective Diode
Diode is a two terminal semiconductor device. One terminal is called the anode while the other terminal is cathode. Anode needs a high potential while cathode needs a lower potential level for the diode to be forward biased. The term forward biased means the diode terminals are supplied with the right voltage level. When the diode is not supplied by

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.

Inverter 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.

How 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

How 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

Purpose 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
