Three-Level (T-TYPE) DC AC Inverter

This solution is a digital control solution for photovoltaic power conditioners, uninterruptible power supply, and industrial three-phase DC/AC inverter power supply. The 3-level (T-type) circuit topology to a three-phase DC/AC inverter can improve system efficiency and reduce the size of the filter reactors.

System Benefits:

• RX66T can simultaneously output 12 PWM gate signals required for a 3-level inverter by synchronously operating 6 channels of GPT timers.
• Gate driver and IGBT design provide efficiency to reduce switching losses.
