The IC IRS2453(1)D is also featured with an in-built oscillator, meaning no external oscillator stage would be required with this chip.

The diodes across the gate resistors are introduced for quick discharging of the internal gate/drain capacitors during their non-conduction periods for ensuring optimal response from the devices. The gate resistors suppress drain/source surge possibility by preventing sudden conduction of the mosfets. The 1uF capacitors effectively keep these crucial pinouts a shade higher than the drain voltages of the corresponding mosfets ensuring that the mosfet source potential stays lower than the gate potentialВ for the required conduction of the mosfets. Pin14 and pin10 are the high side floating supply voltage pinouts of the IC. The simplicity of the design is evident from the diagram shown below: Circuit Operation

The assembler simply needs to connect a few handful of components externally for achieving a full fledged, working H-bridge inverter. The mentioned chip is an outstanding full bridge driver IC as it single handedly takes care of all the major criticality involved with H-bridge topologies through its advanced in-built circuitry. Here we discuss a full bridge inverter circuit using the full bridge driver IC IRS2453(1)D from International Rectifiers. This feature allows the use of smaller transformers and get more power outputs at the same time.Today due to the easy availability of full bridge driver ICs things have become utterly simple and making a full bridge inverter circuit at home has become a kids play.

This avoids the use of a 3-wire center tapped transformer which are not very efficient due to their twice the amount of primary winding than a 2-wire transformer A full bridge inverter also called an H-bridge inverter, is the most efficient inverter topology which work two wire transformers for delivering the required push-pull oscillating current into the primary.
