Matrix Converter

CharacteristicsSimple and compact power circuit. Generation of load voltage with arbitrary

amplitude and frequency. Sinusoidal input and output currents. Operation with unity power factor. Regeneration capability. No storage element is required. Fewer input currents harmonics. One stage conversion(AC/AC) instead of (AC/DC/AC). 1/3 lower loss then conventional system.

Three Phase Matrix Converter

ObjectivesHigh voltage Conversion(AC/AC). Variable Frequency like cycloconverter.

Pic (Peripheral Interface Controller)MicrocontrollerWide range of interfaces includingA/D(up to

~1.0MHz),programmable comparators,PWM etc Built in clock oscillator with selectable speeds. Different pin configuration 8/16/32 Bit Timers. External memory interface USB.

IGBT vs MOSFETIGBTs are preferred in Low frequency applications (100C) Low duty cycles High-voltage applications (>1000V) >5kW output power

Mosfet are prefered in.High frequency applications (>200kHz) Operation at high junction temperature is allowed (
