Most importantly, what is the control signal that feeds the base of Q4 in the bottom left corner?

Where did you get that first schematic in post 1? Kindly give me contact details. Low Side Output Voltage. After that, you can post your question and our dataxheet will help you out.

IR Datasheet PDF –

These work out to Data and specifications subject to change without notice. A shutdown feature has been designed into the CT pin, so that both gate driver outputs can be disabled using a low voltage control signal. C unless otherwise specified. The output drivers feature a high. Can you supply this sysems for me or have you any suggestion.


Otherwise you should build it your self. In addition, the gate driver output pulse widths are the same once the rising under voltage lockout threshold on VCC has been reached, resulting in a more stable profile of frequency vs time at startup.

High Voltage-Current Half Bridge Driver Using IR2153 & IGBT

Could you send email to idriskaka gmail. Feb 17, 4. You’ll need to choose a username for the site, which only take a couple of moments here.

Search Forums Recent Posts. Micropower supply startup current of ? Tolerant to negative transient voltage. This site uses Akismet to reduce spam. Could you advice about Omit part list? I wish to know how Dataasheet can modify the circuit so that I use it for halfbridge resonant inverter for a domestic induction cooker, and how I can incorporate a microcontroller like arduino for the control and power level adjustments.

Because of the IR’s application specificity toward off-line supply systems, this IC contains a zener clamp. This is a link to circuit description and schematic: The IR is a high voltage, high speed, self-os.


After that, you can post your question and our members will help you out. Floating channel designed for bootstrap operation. Feb 16, 1. Low side gate drive output. Feb 16, 1.

Thank you so much for the post. You can discard them. Signal that feeds the base of Q4 is from pickup coil reluctor trigger.

High side gate drive output. Please take appropriate precautions as this project uses lethal voltages! Oscillator timing resistor input,in phase with LO for normal IC operation.

One period is 0. The water is turning continiously via circulation pump with pipe steel. We are able to sell 2 pieces.
