Bidirectional 1kw inverter IC

How IC1 is used in an inverter?

The inverter application requires two outputs that are 180 degrees out of phase. Therefore IC1 is wired to produce two square-wave output signals at pins 10 and 11 with 50Hz frequency, 50% duty cycle, and 180-degree phase shift. The oscillating frequency is decided by external preset VR1 and capacitor C1.

What is an inverter & how does it work?

An inverter provides power backup for mains-based appliances in the event of a power failure. Most of the inverters available in the market have complicated circuit designs and are not very economical. Some of them produce a square-wave output, which is undesirable for inductive loads.

How much rated current is needed for a 240V inverter?

This ripple peak to peak should typically be limited to 20% of the rated current. The ripple current changes depending on the instantaneous voltage the inverter is having to output but is maximal at 50% duty cycle (ie. when the inverter is outputting 200V from a 400V bus). A 1000W 240V output requires a peak output current of 6A.

How much ripple current can a 1000W 240V inverter output?

The ripple current changes depending on the instantaneous voltage the inverter is having to output but is maximal at 50% duty cycle (ie. when the inverter is outputting 200V from a 400V bus). A 1000W 240V output requires a peak output current of 6A. Therefore we should limit our ripple current to 1.2A. You can use the calculations in the video.

What modes of operation does a ti inverter support?

Design supports two modes of operation for the inverter. First is voltage source mode using an output LC filter, this control mode is typically used in Uninterrupted (...) TI’s Standard Terms and Conditions for Evaluation Items apply.

How does a Microcare inverter work?

The locally designed Microcare Inverter is able to anticipate load failure by pre-charging the circuits for rapid transfer of power and change-over. When the grid power returns with a fluctuating voltage, the Microcare Inverter delays the transfer to a set connection time to avoid any load damage.
