Product Information
Hardware Requirements:
The following hardware’s are required in order to realize three phase 50Hz AC inverter.
1. Constant DC source,
2. Three phase six switch MOSFET inverter modules,
3. Controller Section (uC or FPGA),
4. Isolated MOSFET Gate Driver,
5. Three phase load.
Working Principle:
Note: For proper understanding of the isolated MOSFET driver section. Kindly go through single phase H-Bridge inverter document.
1. We need to understand the basic concept in producing three phase AC signal. In a three phase power supply there is a 120 degree phase shift between any two phases.
2. To produce three phase AC using a digital controller such as a microcontroller, it is better to represent the phase shifts in time domain. For a single phase 50Hz sine wave it takes 20ms to complete one full cycle. Now, if you divide that 20ms by 3 you will get 6.66ms, consider this 6.66ms as the time required to produce phase delay between each phases.
3. The time sequence that is to be programmed in to the controller should be as follows to produce three phase. PWM pulses for the first phase should start at 0ms, 6.67ms for the second phase and 13.34ms for the third phase. These are the mere closest values required to produce a 120 degree phase shifted three phase ac wave.
4. For continuous three phase inverter operation, the below shown switching sequence should be repeated every 20ms.
