On different forums, I often find people asking for help in calculating the required turns for a ferrite transformer they are going to use in offline SMPS half-bridge converter s . The half-bridge topology is very popular for offline converters in the power range 100W to 500W, sometimes goin g up to even 1000W. In an offline SMPS half-bridge converter, the line voltage is rectified and filtered and is then converted to high frequency with 2 MOSFETs – one in high-side configuration and the other in low-side configuration. This high frequency high voltage AC is fed to the ferrite transformer to step down the voltage to low voltage high frequency AC which is then rectified to DC and filtered to provide clean DC output. A vital thing to remember is that in a half-bridge converter, the 2 MOSFETs work along with 2 capacitors to create the high voltage high frequency AC. The configuration of the capacitors, MOSFETs and transformer causes the transformer to be supplied half the voltage of the...
Car wheel balancing and alignment Car balancing and alignment both are most important when you driving Car need a balancing and alignment because he run on different road conditions and different path and different situation example,slippery road/hill area/highway/stone surface anywhere so the car wheel may be damaged or unequal So car wheel need a balancing and alignment, If you don't car wheel balancing may be when you run on a road on jerky filling/vibration or jump filling If you don't car wheel alignment your car may be pulling on right or left side smoothly or highly So, this is a most important part of vehicle for easy to driving journey Anybody say what is allignment? You told them allignment is process because when you buy a car these time car have great allignment but you this car run on a different road and different condition so, this may car allignment are not a previous time's means allignment wrong so need this allignment like previous And what is a balancin...
I had previously shown how to drive N-channel MOSFETs in low-side configuration. You can find the tutorial here: http://electel.blogspot.com/2016/12/low-side-mosfet-drive-circuits-and_23.html I’ve been requested to write a tutorial/article regarding high-side MOSFET drive. So, here I’ll talk about N-channel MOSFET high-side drive. Let’s first look at the common low side configuration. Fig. 1 - N-channel MOSFET configured as low-side switch Now let’s look at a MOSFET configured as a high-side switch. Fig. 2 - N-channel MOSFET configured as high-side switch You can quite easily see the difference between the high-side configuration and the low-side configuration. In the low-side configuration, the load is connected between the drain and +V, while the source is connected to ground. Thus, the gate drive is referenced to ground. So by applying a voltage of >7V (for Power MOSFETs) or >4V (for Logic Level MOSFETs), the MOSFET can be fully turned on. Now let’s talk about the high-si...
