Hi, I'm doing a very complex internship and I realy want your help in designing a 2 phase, sinusoidal PWM inverter , 550V , 130 Amp., Iripple=30 Amp., IGBT model no. is (FGL40N120AND), F sw.= 40 kHz, Driver model(UCC37322), output filter (L= 300 uH, C= 940 nF), load: linear motor. the designing of this system in based on a hard switched (...)
A square-wave inverter circuit is extremely simple. A sine-wave inverter is fairly complicated. If you filter a square-wave inverter then most of its power will heat the filter and the output power will be very low. A sine-wave inverter is made with a fairly high (...)
Hi, I have such a question I have to design unity gain buffer as a part of larger schematics. For this amplifier is better to be with source followers for its output stage. It hase to drive RC LP filter. But input signal is almost rail to rail. If I use sorce follwers it decreases output swing. Which are the risks if I use (...)
Hi, I create a simple VerilogA model and use it within a transistor level circuit(a simple inverter),but I found when I add the VerilogA module the simulation process become incredibly slow,and there are some warnnings too. Anybody having encountered such problem? Thanks for your reply.
I don't think you want to build a sine-wave inverter by trying to filter a big 60Hz square-wave. The low-frequency filter components would be enormous, and the output impedance would be poor. One common way to do this is by using a high-frequency PWM followed by a relatively small filter that removes the PWM (...)
I finished my inverter (1000W-230VAC) project ,but i need emi/rfi filter for output side of transformer ......
Hi Use CMOS Charge Pump inverter if output current is not high,such as cat660,max660. ynhe
Does anyone know how you design an inverter output filter to filter the higher-order harmonics? What is the formula?
Does anyone know how you design an LC output filter for an inverter? What is the formula linking the cutoff frequency to L and C? Thanks.
Hi, I'm building an inverter circuit as part of a project I'm doing at college. I'm using PWM to control the inverter switches and eliminate low order harmonics. Does anyone know what type of output filter (passive or active) I need to build to get a quasi-sinusoidal or sinusoidal output?
