The IC IRS2153(1)D which is fundamentally a half bridge mosfet driver chip can be actually used for a number of different interesting circuit applications such as boost converters, solar compact inverters, and if two of them are coupled can be even configured as a full bridge mosfet driver circuit. Let's learn more about this interesting device.

The half bridge drivers I have are IR2184. I found a circuit diagram someone else has designed using the same driver ICs but I have some questions about it.

Driver Circuits Driver circuits are most commonly used to amplify signals from controllers or microcontrollers in order to control power switches in semiconductor devices. Driver circuits often take on additional functions which include isolating the control circuit and the power circuit, detecting malfunctions, storing and reporting failures to the control system, serving as a precaution against failure, analyzing sensor signals, and creating auxiliary voltages. Thyristor Driver Circuits In thyristor driver circuits, appropriate control signals are used to generate gate current pulses in order to trigger the thyristor. A transformer often isolates the control circuit from the high voltages of the power circuit. Figure 1. Principle of a thyristor driver circuit The firing pulses are repeated several times in order to ensure that the pulses exceed the thyristor's latching current. The latching current is the minimum gate current required to trigger the thyristor. For the thyristor to turn on, the gate pulse must continue until the current through the thyristor reaches the holding current, the minimum current required for the thyristor to remain in the on-state. MOSFET and IGBT Driver Circuits IGBT and MOSFET drivers are very similar in that both components are controlled by voltage (charging the gate capacitor). Table 1 below shows typical control voltages for both types of drivers: Primary side of driver circuit On the primary side of the IGBT half-bridge driver circuit above, input signals are received and error signals are sent back to the controller. Signal processing that takes place on the primary side of the driver circuit enables short pulse suppression in order to minimize glitches, prevention of both IGBTs in the half-bridge turning on simultaneously so to avoid short circuits, and monitoring of temperature and undervoltages. Secondary side of driver circuit On the secondary side of the driver circuit, input signals are amplified and used to control the switching of the IGBTs. Overcurrents are monitored to detect shorts in the power circuit. This is done by either comparing the collector-emitter voltage VCE to a preset threshold or by monitoring the signal of a current sensor. If overcurrent occurs, the secondary side of the driver switches all the IGBTs off and sends an error signal to the primary side. Output Stage of Driver Circuits The gate emitter capacitor is charged and discharged through the gate resistor by the driver. This determines the switching speed of the IGBT. Figure 3. Output stage of a gate driver In the diagram above, Rgon represents the external gate series resistance at switch-on and Rgoff the external gate series resistance at switch-off. The higher Rg the slower the switching process.
