What are the second case PWM signals ? If you are referring to the complementary switches of the Full Bridge, a simple inverter might do the job.but how to make those second case PWM singals most easily?
Delay Matching is the dead-time those people were talking about. Figure 6 explains it pretty well, I think.but many people have written online that the IR2110 includes dead-time in the circuit internally but the datasheet is not full of information, it does have some timing value that I don't understand what it is, it's named "Delay Matching, HS & LS Turn-On/Off" and is specified as 10nS.
Depends on the switching times of the MOSFETs and the internal dead-time of the driver. If MOSFETs switch ON/OFF faster than the dead-time, you do not have to worry.I don't know how to determine the requirements for dead-time in this case, do I have to worry about that?
Yes it is true. The gate resistor will slow down the turn ON while the diode will fasten the turn OFF, in general...I have read that the diode and resistor that I have put in series with the MOSFETs gates is suppose to introduce some dead-time, but I can find no info on the validity of that statement
I have heard that if a heating coil(it isn't a coil as in inductance coil, it's simply a resistive heating element wound as a coil)
At those frequencies, the inductance will most likely show its influence i.e. will NOT be a resistive element as you seems to want. It seems that you want a heater, but the coil+those frequencies suggest you are trying to do an induction heater.PWM frequency of 100kHz, but I might also use something more along 1kHz
I have heard that if a heating coil(it isn't a coil as in inductance coil, it's simply a resistive heating element wound as a coil) is supplied with current in only one direction the heating of the coil is uneven on some ways, but that if the current is alternating in direction the heat distribution across the coil will even out.
