    Step up 5vdc to 72 volt ac/dc

    1. I use a medical therapy device that needs 72 volt ac input. 2. Need to drive the medical device from a 5 volt dc Powerbank for mobiles that are readily available in markets 3. For that, I need to somehow step up the powerbank output from 5vdc to 72volt (either ac or dc) 4. The max load...

    Boost converter Controlling problem when transfer from light load to heavy load

    I built a boost converter to boost voltage from 200V dc to 400V dc. Power rating is 5kw, I added a PID to regulate the voltage. The problem is, when going from light load to heavy load, output voltage causes overshoot. After going to heavy load, further load addition has no problems. For ex...

    Voltage regulator for battery powered microcontroller

    Hi folks, I think what I have is a fairly simple question, yet I've spent so much time Googling, that I've completely lost track of what is what. I'm looking for an affordable voltage regulator to power an ESP32 from a number of AA or AAA batteries. I have bought a pair of these (Dutch...

    How to solve that Pspice circuit capacitance component problem ?

    Hi its a boost converter circuit. its mean it make increase applying voltage on the output . I am applying 201.6 volt and I should see approximately 650 volt on the output. But I have a problem about capacitor. When I use basic capacitor, I realised that my capacitor is not working well...

    Inverting Boost Converter that Short Circuits?

    Hello, I have an inverting boost converter which is giving me some difficulty. It can be found on pages 1 and 3 of the PDF attached (the non inverting works fine). This inverting boost converter should (and has in prototype) produced -100V - 0V without any difficulty. All control signals are...

    Better approach for powering up sensor nodes ?

    I have a sensor node containing an MCU & radio running at 3.3 V and a sensor running at 5 V. What is the better approach for powering up the system (in terms of efficiency, stability, etc.) : 1. High Voltage Battery + Buck Converter or 2. Low Voltage Batttery +...

    MOSFET for boost converter

    I am making a boost converter following this Tutorial but I don't have the exact MOSFET. I have 2 motherboards laying around and they have some MOSFETs on them some of the names are: P3055, K3918,6670AL(datasheet inserted). There are high switching speeds but the datasheets don't have the max...

    Grounding problem is coming between boost converter and mosfet driver

    I am designing a boost converter which is rated on 100 watts, 12 volts to 24 volts, switching frequency is 20 khz, in open-loop conditions. when I give the input power supply to the circuit as 12 volts, my driver (HCPL 4506 Mosfet Driver) will take VCC as 24 volts due to My microcontroller can...

    How to wire up PWM control chip to DC DC boost circuit

    Hello, I need some help connecting an 8 pin current mode PWM controller to my boost converter circuit. Specifically this one. I have used controller IC's with integrated switches to make boost converters before, however, the amount of power I need to run through the circuit requires an external...

    Flyback diode problem (heat) in boost converter

    Hello! I need to decide what I should understand/learn to go ahead with my boost converter and stop killing my MOSFETS in the wild. I'm not a engineer (at least not one of the 'right type') and electronics is just a hobby. I have a boost converter that's basically scheme.jpg (MOSFETS are...

    DC-DC Boost Converter Switching Frequency

    hi guys, currently i'm want to design a dc-dc boost converter but i don't know what is the best frequency value that i need to use in this converter. can someone advise how to find the best pwm switching frequency? i need a justification why i supposed to use that frequency value on my design.

    which type of dc to dc converter to use to convert 5V, 80mA input to 3V 300mA output?

    Hi, I am working on a solar panel whose output maximum specifications are 6V, 100mA ( nearly 0.6watt). Practically these values came to 5v, 80mA when tested in afternoon sun. I want to run a motor whose operating voltage is (3~12V), no load current is 180mA. I would like to know...
