Technology Development of a 1200W Bi-Directional Inverter with Unlimited Current Sharing Capability for Portable Power Station Application

Battery powered Portable Power Station (PPS) becomes popular in recent years because of its multiple benefits to consumers, such as portable, environmentally friendly, no noise, no need for gas. However, the existing PPS suffers from two fundamental limitations: (1) longer re-charging time, such as 5 to 7 hours; and (2) limited power capability. This project will develop a bi-directional inverter that will generate the required AC voltage from Battery. When it operates at rectifier mode, it can charge the battery from 0 to 80% in one hour. Another unique feature is that several PPS units can be connected in parallel to provide multiple times the total output power. It is expected that when the project is finished, a bi-directional 1,200W inverter will be designed and three experienced power electronics designers will be trained. It will significantly improve the competitive advantages of DigiQ Power and allow it to hire more engineers in Ontario.
