| Summary: | 碩士 === 東海大學 === 電機工程學系 === 100 === In this paper we present the design and through the TSMC 0.25μm HV process to achieve a single-phase bipolar voltage switching DC-AC inverter. The design of the main structure is PWM bipolar switching technology and a level shift circuit connect to full-bridge circuit to do the DC input voltage to the AC output voltage control. A supply voltage and temperature-independent bandgap reference circuit is used in the inverter that has a output voltage of 9.4V/60Hz of sine wave. The AC sine wave voltage is provided to a small AC LED load. The chip area is 1.9 x 2.05mm2. Circuit simulation verifies the performance and feasibility of the conversion system.
