TIDA-00122, Automotive 200-VA High Frequency Inverter Design

TIDA-00122, Automotive 200-VA High Frequency Inverter Design. This design presents a low-cost, small size, robust 200-VA DC to AC inverter based on MSP430 and UCD8220-digitally managed push-pull controller. It is targeted towards car inverters and small-segment inverters for commercial applications. In this design, UCD8220 is used for a boost stage to get 250-V DC from a 12-V battery. The MSP430 acts as a host controller and provides a 100-kHz clock to UCD8220 and drives for output DC-AC bridge. This inverter has a peak efficiency of 90% and has natural cooling and does not require a fan for cooling
