| Abstract | ||||
| High-performance high-frequency inverter systems for voltage source applications such as UPS represent a demanding application that cannot be easily realized using conventional PWM inverter modes. New controller structures are necessary to cope with stringent voltage regulation and distortion constraints in the presence of nonlinear loads. This paper presents a simple but intelligent hysteresis controller. It utilizes all possible inverter topologies in addition to feed-forward strategy to achieve low output ripple, minimum switching frequency and excellent transient performance. These features were not available until now. The result verifying the concept, using pspice program for practical electronic control circuit and power devices, are presented Although this paper explains the implementation of the 3-phase control and power circuits that can adapt itself in case of nonlinear and unbalanced loads. | ||||
