I am a student learning power electronics.

Please understand that I am not good at English, so I am using Google Translator.

I'm making a Half-Bridge using IR2110.

But I'm having trouble making the circuit.

For the IR2110 input, a function generator is used to input an input of 10Vpp Offset 5V and an input of 6Vpp Offset 3V on the high side.

However, the gate driver signal is not output.

Please take a look at the Half-Bridge circuit diagram.

Please help me by attaching a photo.

 

You don't have a schematic drawing?

 

Welcome to AAC!
Which voltages are you supplying to which pins of the IC?
How much dead time is there between the Hin and Lin signals?
What load is being driven?

Please help me by attaching a photo.

A photo of what?

I referenced the circuit from the Tahmid's blog.

A photo of what?

I entered High Side at number 10 and Low Side at number 12.

I was going to ask about how to give dead time.

I connected 100 ohms between the emitter and collector of the half-bridge.

That picture is a circuit I made on a breadboard.

Which of your 10V and 6V sources did you use for Hin and Lin?
What voltages are on the Vdd and Vcc pins?
How much current can the Vcc source provide?

? MOSFETs don't have emitters and collectors.

Please provide a schematic of your circuit, marked up with the voltages at the appropriate inputs.

I gave a square wave of 10Vpp, Offset 5V to Hin pin 10, and a square wave of 6Vpp, Offset 3V to Lin pin 12.

Vdd applied a voltage of 5V through LM7805, and Vcc applied a voltage of 18V.

It was difficult to measure current with that scope, so current could not be measured.

Sorry for the confusion. I am trying to drive Half-Bridge using the G4PC4OUD chip, an IGBT device.

The address posted by Mr.MaxHeadRoom is correct, and I am uploading the schematiccircuit.

Thanks for your help

You only need to drive HIN and LIN with the same levels as VDD, i.e. TTL input voltages, not your strange offset voltages. You may have damaged the I.C. doing that!

So since the VDD voltage is 5V, does this mean that the 5V pulse waveform should be used as the input waveform for High in and Low in?

I will take a picture of the waveform in the lab and upload it later, so please take a look at the input waveform.

Yes.

Hin and Lin pulses must not both be logic high at the same time, as that will result in 'shooot-through', i.e. a short-circuit through the drain and source paths of both FETs.

 

I made a shematic two of these half bridges you might find useful

 

The HIN and LIN have to be toggled with a dead time of 1us

 

get LTSpice and the zzz library!

sorry. I think I misunderstood the input signal.

I drew the input signal using Powerpoint.
In the picture, it is assumed that red is high input and green is low input.

Are you saying that the input signal that Mr. Alec_t and Mr. scottsman mentioned should be included as shown in the photo?

Additionally, I would like to output a waveform similar to the Half-Bridge theory on YouTube using only one Half-Bridge.

Below is the address of the relevant YouTube channel.

 

Don't be sorry!

when V5 is high V4 has to be low and the dead time is the time INBETWEEN toggling!

I don't understand gate drivers.

If I input the same pulse waveform, wouldn't the IR2110 chip convert it and convert one pulse to high and the other pulse to low at the IGBT gate through the gate driver output?

 

No this confused me too. you pulse BOTH the (HIN) AND (LIN) with high (5v) pulses alternatly with dead time of 1us! to avoid "shoot through"
