Step 3) Gate driving! I'm driving the MOSFETs using couple of logic gates. Wonder how you'll achieve it because pure NMOS switches require gate voltage above Vout, in other words an auxiliary power supply. Most charge pump converters are using CMOS switch topology to avoid it.
I want to design a pure sine wave inverter. Input: 48 volt 150Ah battery output: 230volt 50Hz pure sine wave what topology should i select? low frequency or high frequency? what are the advantages and disadvantages? LF: 48v>>Hbridge(spwm)>>lowfrequncy transformer>>230v sinewave. HF: 48v>>push pull high frequency transformer
I want to drive a PMDC motr. I only want to drive in one direction only. motor specifications 2HP 120v 14A Input 120V DC what topology should i choose?
Dear All, i am Designing a DC-DC CONVERTER for the UPS Application. 1) Input :480V PFC Bus/8 Amp 2) Output:48V/50 Amp 3) Efficiency:95% 4) Less component Count. The converter should be off Inverter Type. Suggestion advice & Web links of innovative idea & magnetic Help pls Thanks Deep
Hello, I have to desgn 115-305 Vdc input and 28 Volts output 450 Watts DC-DC converter. Can you offer a topology for this application? The input voltage range is wide, it makes difficult to choose a controller. Thanks.
Hi, Can you suggest me a SMPS topology for the following input: 85 to 264 VAC Output 1: 24V, 8A Output 2: 12V 2A Thank you
As said above, decision to select Linear Regulator topology instead SMPS, may me merely casual. However, there are some reason which could contribute to avoid selection of circuits based on switching. If we consider that - differently from LAMP devices ( which are able to convert energy to heat ), LEDs doesn´t support operate reliably ou
which topology is mostly used for charging VRLA battery systems in dc to dc ups application.... And whether mostly preferring isolated or non-isolated for the battery charger..... and why? I need know this information for designing the battery charger for high rating UPS application...
Which topology is suitable for this project? I want to start with half-bridge and multiplier, anyone give advise?
Folks, I'd like to choose a DAC topology to have below spec: 1. 100KHz sample rate 2. 10 bit 3. minimum DNL but much relaxed requirements on INL Can anyone suggest a topology to have smallest area? Thanks, SQ
Guys, I need to design 12Bit 1MSps SAR ADC with input having of 0~VDD range and 20KHz. Input will be coming from selection MUX. Can single-ended topology cover for this spec or should go with fully differential topology? And if I pick fully differential topology, I need to single-to-differential converting for ADC input. (...)
Vp/Vs = Ip/Is Np/Ns = Vs/Vp Unfortunately both "formulas" are wrong. A converter with variable input voltage and intended constant output must involve a method of voltage regulation, either by PWM at the primary or a separate secondary switcher. The selection of a suitable converter topology also affects the transformer dimensio
Hello All. I have a question regarding the topology I need for my application. I want to charge 750 microfarads up to 1200V for a coil gun application. I am going to be using (rectified) 120Vac single phase. I want to do this with a dc-dc sitchmode power supply. I need to pick a topology though. I think for the charging time I want, I need a
it depends on the level of detail you want to see, and what aspects. do you need a schematic and then layout? that will influence software choice too. topology selection: PSIM / Simulink component selection? Ridley 4-5-6 power electronics behaviour? probably PSpice controller design? probably simulink. EMI ? maybe (...)
Hi, I need to design a 250W DC/DC converter from 12V to 100V. I'm here to ask you experience on the topology selection. Here the main specs: Vin = 10-18V Vout = 100V Pout = 240W Tambient = 125°C The load will be highly impulsive (you can immagine a square pulse load with 25% of duty cycle) and I would like to use on-the-shelf m
A good complement to hand calculation is a practive which Barrie Gilbert called "Foundation Design" It uses spice and a model library where you could activate specific physical effects in the model. So starting the circuit design by topology selection, hand calculation, dimensioning and then simulation which the most simple, ideal device mode
Eg. * Determine the location of large block * Macro placement, such as RAM, HardIP, analog block ... * Determine the location of IO pad * Power topology selection
this is a practical question. I want to select 1 of 2 antenna at a time and send 2W power to it,which switch topology is better? Ref Open or Ref Short?
what is optimally ? Best performance - class A Lowest q.current - class B(or C) Usually you choose the smallest current that gives you crossower distortion, pertinent to your design. That depends on your circuit topology ang output transistor's choise.
Dear Amic, As sunking mentioned, to achieve high PSRR and low output impedance cascode+class AB may be the best choice. Its output impedance can be down ~1kohm, if lower impedance is requirested parallel negative feedback topology may be proposed. Bg,
