본문내용
less suited for transformerless full bridge PV inverter
Bipolar PWM의 특징
1. Only two voltage levels are there in the output
2. It requires only one sinewave
3. It is easier to implement
4. The harmonic performance is poor
5. requires large filter at the output
6. Switching losses are more
7. Not much of use in the modern era.
8. However, better suited for transformerless full bridge PV inverter.
