Solar power inverter(South Africa) AZX-300VA

The AZX solar power inverter adopt output bridge, producing 50Hz sine voltage and
current signal. If the above switch conducts the below one, a positive voltage
will be on loading between terminals, otherwise a negative voltage. In this
case, only one switch can conduct at a certain time. One switch can be converted
to PWM high frequency, the other one to below 50Hz low frequency. Due to the
bootstrap circuit depends on the low-end devices, the low-end devices are
converted to the PWM high frequency, while the high end ones to the below 50Hz
frequency. These switching devices will inherit reverse recovery current from
all other devices when switch conducts, making it an ideal choice for quick
recovering Super-junction devices such as 600V FCH47N60F. Therefore, the IGBT
can reduce the total loss of the output bridge, so as to improve the overall
efficiency of the inverter.
