You are maybe one of the individuals who are asking how much savings on inverter refrigerator. Inverter refrigerator technology is getting popularity nowadays. What is the difference between it and the traditional refrigerator? How much saving to expect by choosing the inverter type? How long to get the return of investment in using the inverter one? Let us answer all

There are some factors to consider in calculating MOSFET power dissipation. When the power dissipation is known, it is possible to compute the junction temperature of the MOSFET. Important to take that a MOSFET installed with no heatsink has different computation strategy compared to the one with a heatsink. Small current or low power MOSFETs are usually mounted to PCB

Two of the most common three terminal semiconductor nowadays are MOSFET and BJT. MOSFET is metal oxide semiconductor field effect transistor. It is a variant of FET. BJT on the other hand is bipolar junction transistor. It is worth to discuss MOSFET and BJT comparison to understand which part to use. Read below comparisons. 1. Application of MOSFET and BJT

It is very common application to drive a relay with a MOSFET. From household applications to automotive are using this circuit. There are some aspects to consider like the stress on the MOSFET, the level of driving voltage to guarantee MOSFET saturation, the level of the actual voltage applied to the relay coil if enough to meet the requirement and

Circuit breaker is the most common short circuit and over current protection. It is a simple electrical device but very important to safety. The most common question is what must be the current rating of the breaker to safely protect devices during abnormal condition. Basically, this is not the only thing to consider in selecting a circuit breaker. Below are

1. Select Inductance Value a. Define the switching frequency for the boost converter Example: Fsw = 300kHz b. Define the input and output voltage Example: Vin = 12V, Vout = 24V c. Determine the duty cycle Dutycycle = 1 – (Vin / Vout) Example: Dutycycle = 1 – (Vin / Vout) = 1 – (12V / 24V) = 50% d.

If you are planning to make your own inverting buck-boost but don’t know where to start, therefore this inverting buck-boost step by step design guide is right for you. A buck-boost converter is a DCDC switching converter that combines the function of a buck and boost converter. Inverting buck-boost is a variant wherein the output is negative with respect to

In order to derive the primary current of a Quasi resonant flyback, it is important to know the waveform of the current. Quasi resonant flyback primary current is rectangular in shape. It will rise linearly when the flyback switch is ON while drop immediately to zero once the switch is turned OFF. Below figure do more the explanations. Quasi Resonant

One of the very important aspect to look at in dealing with quasi resonant flyback transformer is the saturation. A quasi-resonant flyback transformer is not actually a transformer that we usually know. A transformer will transfer energy from the primary to the secondary at real time. However, the flyback converter will store energy on the primary and then transfer that energy to the secondary somehow. This action makes a flyback transformer prone to saturation if not properly been designed.

You may not know how to use MOSFET as reverse battery protection. The most common method is using a diode. However, diode voltage drop is high and this will creat issue in low voltage circuits. That is the reason many use MOSFET as reverse battery protection due to its very low on state voltage drop.
