This solution is for digital control of photovoltaic power conditioners, UPS and industrial 3-phase DC/AC inverter power supplies. You can increase the system efficiency and reduce the size and weight of the filter reactors that cut harmonic components by applying a low-loss SiC power element and 3-level (T-type) circuit topology to the inverter circuit.
|Output frequency||50 or 60Hz|
|Input voltage range||750Vdc、600～850V|
|Inverter switching frequency||20~50kHz|
|Cooling Method||Natural air / Foced air|
|PWM mode||2-Level / 3-Level|
The PWM output voltage waveform of the 3-level inverter more closely approaches a sine wave.
There are fewer harmonic components in the 3-level inverter output PWM voltage, resulting in smaller, lighter and lower cost filter reactors to cut the high harmonic components
40% reduction in reactor volume and weight for 3-Level (50 kHz) compared to 2-Level (20 kHz)
The switching operation of the power components is performed at half the DC power supply voltage, effectively reducing switching losses and increasing efficiency
