Inverter Definition and 174 Threads

Hi, I have been having this question for a long while. From Pozar's book (Microwave Engineering), on page 336, when he was solving for the resonance response and the Q factor for a Lamba/2 resonator terminated by an open circuit, and coupled to the feed line through a series capacitor, at some...

Good afternoon everyone! I've exhausted my initial ideas for supporting 1500 watts of power in the trunk of my car, for intermittent use with a wall plug connection. My first thought was a simple power inverter, however, ideally I won't be running this power from my car battery. This has proven...

What is the basic reason of unbalance output of an inverter, even the output connection is open and the IGBT is ok. Can anybody tell me what is the problem? Co operation is always encouraged.

Hi, I am building a Full-Bridge Inverter using four IGBT and four drivers for each IGBT. Driver is HCPL-3120, all four drivers are supplied with 15VDC isolated supply. I am switching using M bed micro controller LPC1768 generating two PWM signal working alternately, first signal turns IGBT 1...

This video describes my issue pretty well (I have it set to start when he talks about my specific situation): ETA: looks like the board doesn't allow the video to start at the specific time, the important stuff begins around 5:30 Our applications are a bit different as his design is for...

Homework Statement Constructing a NAND gate as an inverter. Homework EquationsThe Attempt at a Solution I've attached the image at my attempt to construct the circuit. The output is always on, which it should be except when both inputs are zero. Could someone explain what I am doing wrong...

Hi guys can anyone please tell me that it is possible with an air conditioner of type inverter to put less energy than what the piece is receiving as heat. So let's say that on the inverter it says output KWh/ input KWh =4. Henthalpy= G+TS 4*Hinput= Houtput inside the house So to heat my...

I'm building a boost inverter, and when I connect two trasnsistors, an npn and a pnp, to the output resistance, and connect these two transistors to voltage it works. Now, when I connect the other two transistors and connect them to ground the boost stops working. Would anybody know what's going on?

I'm currently reading a paper given to me by my professor to expose to class. The problem is that I don't understand it very well! I'd like to see if you guys can help me. The paper I'm reading is "A boost dc-ac converter: Analysis, design, and experimentation" I've found the paper on the...

I'm doing research with my professor on H-Bridge Power Inverters, I noticed that the more load we put on the device the better the wave looked (by better I mean cleaner, not as much noise). By ohm's law the current should be falling; would this not happen only if the current were rising? I...

Hi, I found a great generator, Earthquake 800 watt inverter style that is quiet and runs 14 hours on a gallon. BUT the Bosch SDS drill kills the engine, even if you barely pull the trigger. https://www.amazon.com/dp/B00FL89I2W/?tag=pfamazon01-20 I have a 750 watt inverter I hook up to 12V...

how would yo connect a 2 input nand gate to form a basic inverter? i constructed a truth table. i know that the two middle ones don't count because the inputs have to be of the same value for an inverter. but what conclusion can i draw from this?

I am creating layout of cmos inverter in cadence virtuoso using 0.18um technology. channel length is 2Lambda = 0.18um I read that contact should be 2Lamda X 2Lambda that is 0.18um X 0.18um right but my LVS Check is throwing error telling that contact must be 0.22umX0.22um whats might be the...

I have just begun my power electronics class, but have already seen what an inverter is. My question is: is there a difference between the topologies that function with photovoltaic systems and wind energy ones? Thankyou

I am simulating cmos inverter in CADENCE I am getting a sharp spike when output is going from low to high and spike became more amplified like when i made rise time and fall time of input rectangular pulse signal very low . . .can somebody explain why this happening ?

Hi~ Actually I am fine with calculating the delay but I haven't got the concept clearly enough. Both nmos and pmos have their equivalent RC models. I understand how the RC model of nmos works when its on or off but I don't get how the pmos turns out this way. When its off, the upper part...

Hey guys, I need to make a power inverter that will take in .1-.3 volts, and the output needs to be as high as possible.

Hi, could someone confirm whether I am right in thinking that for a PWM inverter, the input sine voltage is converted to DC using a bridge rectifier? Does this DC voltage then have a value which is the same as the PEAK value of the sine input? Is the DC voltage then 'chopped' using IGBT's to...

Hi, I understand that the PWM inverter drive system first uses a diode bridge rectifier in order to convert the AC incoming into DC before using an inverter to convert this DC into PWM for use on the induction motor. Could someone please explain in simple terms how the PWM inverter section...

A panel put out over 30.7 volts, say 34 volts and I have a micro-inverter that require a voltage of 11-30 to work. Other than shading some of the panel, is there a way to half the voltage from the panel without as much loss from shading some of the cells to work the inverter?

Hey guys. I am simply trying to derive the equation for Vout in a PMOS inverter (attached). I know that in an NMOS inverter (which has the resistor in top of the transistor instead of the bottom) the equation for Vout is: Vdd - id*rd. But how does the resistor being in the bottom change...
