DIY 6kw induction heater with delayed lock loop(DLL)and pulse density modulation control
this is another series resonant induction heater ,current limiting and power control is done with pulse density modulation algorithms, for tracking the resonant frequency, for the first time it use a delayed lock loop(DLL) instead of commonly used PLL ,the main advantage of using DLL is its very short locking time that increases the reliability of the switching devices ,as shown in this video the heater can withstand and track very fast changes on the resonant circuit,like shorting the work coil and beacuse of using pulse density modulation , there's no hard switching at any point and we can choose low rated components:

DIY 50kw series resonant induction heater with pulse density modulation control
Просмотров 797Год назад
the common way to control the power of induction heater is detuning and this will increase the switching loss but this heater uses a new power control method ,the resonant current is controlled by skipping the inverter pulses ,and switching loss always minimum

    Can you share the circuit diagram of the PDM Controlled induction heater? it works perfectly. I also designed PLL controlled 100khz induction heater circuit but controlled the power using UCC3895 phase shifting Full Bridge integrated circuit. However, I could not solve the snubbar problem. I also used a second method by checking the dc bus current and voltage of the Full Bridge inverter circuit. You used a different transportation method. It caught my attention. Thank you.🙂

    Hello my dear friend. Your project is great. I could not fully understand the serial-parallel topology. I would be very grateful if you could send me the schematics by e-mail. If you can't do that, my question is, do I have a chance to catch resonance by changing the frequency of the power circuit instead of this series circuit?

    ebay 20 amp 12-32 volt board: i figure resonance is from the 2 toroid inductors and the 2 .3 uF capacitors. the coil(not supplied) is the series resistance. I had trouble with the coil connecter smoking. I resoldered and retightened. I soldered joints that had resistance. I used a D cell for the coil form. 9 turns. A bit better still. Then I soldered the coil to the board. I put a 3/8 bolt in the coil on cardboard. After about several minutes the bolt was orange hot. I shut off the silicon valley power supply. The 1000 watt board(24 volts) might start to have problems. 2 capacitors is less resistance . ok demonstrator board. recheck capacitor - under load more?

    As the load changes so does the resonant frequency. This requires a PLL to lock on to it and feed back the right frequency to the power section. Some old guy on YT who made a similar system. The output of the PLL goes to a VCO which drives the Power driver (PD). The PD in this case must be a Full Bridge to drive the resonant circuit of the output coil. The PLL output is a low frequency level which will also drive a motor shaft that moves the core of the resonant inductor coil in order to change the frequency. So if anybody there wants to make this self adjusting heater then just make a block diagram to follow what I wrote. I cannot put drawings in this post. Once you make the block diagram you can also design the schematic for it. If you cannot design the schematic then it is no good if he gives you a copy because the system is too complicated for someone who does not have the skill to design the circuit.

    • @MOJTABASHOMAL
      @MOJTABASHOMAL 4 года назад

      nice description but not exactly what i made 1-its half bridge inverter 2-this topology as it called series-parallel ,has two seperate resonant frequency ,main pll tracks the paralell resonant ,another locking system sees the inverter phase diffrence and tune it with motor to have a correct power factor another advantage of this tunning system besids tracking the parallel resonant,is it can deviates from paralell resonant to have a prpoper matching its very helpful when you wanna melt steel becuase it needs very wide range frequncy to deliver the maximum power and as you said it can't be undrestood only via schematic it needs block diagram
