rectifier

Simulating RF rectifier in ADS (2.45 GHz, 5 dBm). Using HSMS-282E gives 11% PCE, SMS7630 gives 21% PCE. Matching is correct (good S11). Using SPICE models from datasheets. Load = 2 kΩ. Using HB with proper Pin/Pdc equations. Why is PCE so low? What am I doing wrong, or are these values...

Hello, I have been experimenting with half wave rectifiers but I am having an issue and would like to see if anyone can help me troubleshoot it, or if I am completely wrong and need a different circuit. I want to only let positive voltage go through my circuit and get rid of all the negative...

In a rectifier and RC filter, which combination of waveform, bi-polarity, inductor/cap, and transformer-type will give the least ripple in the output? My input is 100 kHz AC supplying a transformer. I have control over the supply voltage, wave shape, and polarity, over the transformer type, and...

Let the following circuit: The diodes and SCR are supposed to be ideal, the supply source v(\theta) = V_m \sin(\theta) , let \phi \in (0, \pi) be the angular gate pulse for T1 and \pi + \phi be the angular gate pulse for T2, i want to understand why in the interval \theta \in (0, \phi)...

Hi, I'm building an engine driven generator to charge a 48V 300Ah LiFePO4 battery bank. The generator will output three phase power at 90 Vac line-to-line, 170 Hz. Electrical output power will be about 10kW at best efficiency point. I'm looking at options for how best to use this output to...

Hello all, I have been checking this 30 kW Vienna PFC rectifier reference design and didn't understand why all of these filters are used for this kind of application, i mean half of the board is inductors and capacitors for the filters. Can someone explain what type of filters are used? and...

Hello I have this problem as mentioned in the subject, which happens when I connect the transformer to a " 3-phase full wave controlled bridge rectifier ". I have a fully controlled bridge rectifier board of (TYN812RG) thyristors, and I want to trigger it through some firing board which I am...

I'm new to electronics and decided to learn something new by trying to put together a small rectifier circuit that converts 24VAC to DC. So I put together a little full-wave rectifier circuit that consists of four diodes and an LED and ran into an issue when I tried to measure the DC output...

Hello, I'm working on a little side project for my home thermostat. I recently bought a nest smart thermostat to replace my old "dumb" thermostat and ran into an issue with the wires. I don't have enough wires to accommodate all of the thermostat functions. Running new wiring is not an option...

i have taken on the project of refurbishing my own car alternators which died on me over the years. all these alternators are compatible with 1990 mitsubishi eclipse and come in 65/75/90 Amp configurations. as seen in the attached pictures, some stators come with 3 single wire windings and...

I have a device that runs on -5v DC but I only have 120V AC. I need to build a power supply that can convert 120v AC to -5v DC. I need to draw the best power supple and indicate the wave form at each stage.

input is 15kV 15ma (as is on attached picture) going into capacitor bank diode is a Single Phase high-voltage diode rectifier silicon reactor Model: PRHVP 2A-20 (HVP 20 HVP2A-20) 2A20KV Size: 18 x 19 x 75mm (Height * Width * Length ) Operating Temperature: -40 ° C ~ + 175 ° C

Good day, I have a design problem I need to complete. Unfortunately it has been a long while since I have done a design in that area. I need help with this design.

Hello, I found a circuit (transmitter) design that would create an oscillating magnetic field. Another circuit (receiver) would pick the induced voltage up and amplify it. Now as I understand it, the oscillating part has only positive voltage. But in the receiver part they use a recitfier. Why...

Hello guys, how are you all doing? During the past few months I've been going through the Textbooks AAC has published, experimenting with some minor circuits and even PIC microcontrollers. I've learned a lot during the process and decided to do something a bit more challenging - make a basic...
