DC to AC Pure Sine Wave Inverter
Here are project reports on how to manage the various design needs of a inverter for a power ups. Even Solar Energy systems need inverters to create AC Sine Wave Power Supply from a DC Battery Array.
Creating a Efficient and Inexpensive Inverter – By Jim Doucet, Dan Eggleston, Jeremy Shaw
This report focuses on DC to AC power inverters, which aim to efficiently transform a DC power source to a high voltage AC source, similar to power that would be available at an electrical wall outlet. Inverters are used for many applications, as in situations where low voltage DC sources such as batteries, solar panels or fuel cells must be converted so that devices can run off of AC power.
PWM Techniques: A Pure Sine Wave Inverter – Authors :Ian F. Crowley and Ho Fong Leung
This report documents the development of one component of an uninterruptible power supply, the DC-to-AC inverter. Through the use of analog signal processing techniques, a prototype which efficiently and accurately emulates the pure-sine wave power present on the power grid was created. The three-level PWM system within this report is created with the possibility of a feedback-regulated system to be implemented in the future.
