"This circuit can't work, because the gates are not driven."
The gates are driven by the signal coming from Ho1, Ho2, Lo1 and Lo2 of the EGS002 SPWM driver IC
The 1N4148 diode I'm talking about is the reverse diode used at d gates of the FETs, it is a fast recovery diode which is best for high...
I started a Pure Sine Wave inverter project which I am to use egs002 for this purpose. I have followed the datasheet carefully. I savaged a transformer from an old ups, the transformer is 15-0-15/220v which is meant for a 24vDC 1.2kv ups. I rewind this transformer to 0-7.5/220v to use for my...
Thanks for the clarification audio guru, I am planning to use two NPN transistor TIP122 on both side, the output from the Sg3524 will be connected to the base of the transistor to switch it on and off, then the collector will be connected to the wire from the transformer, and the emitter will be...
I guess the problem with my project is the overvoltage from the transformer which is exploding my mosfets, because there is no load connected to the output of the transformer when I'm testing it. I guess when a load is connected, there will be no room for storing too much of energy that will...
Thanks audioguru for your time. If I may ask, what is the main reason causing my mosfet to explode? Is it that the voltage from the Sg3524 is not enough to turn on the mosfet? Or the amp of the battery is too much that is flowing through the mosfet? I am using 12v 100Ah battery, cos I notice if...
I'm not a Chinese, I'm a Nigerian and I'm new to electronic stuff, I'm just a hobbyist. I have correctly connected the mosfet, first pin is gate, middle pin is drain and third pin is source. I used 10k resistor between gate and source, I connected source to ground and drain to the transformer...
There is MOSFETs version of the tutorial. Here is the schematic of the mosfet version. **broken link removed**
I did my mosfet connection the same way its shown in the schematic.
Thank you for your quick response. What can I do to power my inverter? Should I substitute the mosfet for Motorola 2N3055 transistors? Or is there any other IC that I can use for oscillating?
Hello engineers, I am I newbie, want to make an inverter. I am following the tutorial at https://www.instructables.com/id/250-to-5000-watts-PWM-DCAC-220V-Power-Inverter/
I was able to setup the driver stage successfully, but I am having problem with the power stage of the schematic. I used 4...
