Abstract
Regular sampled pulse width modulation and space vector modulation are often presented as two alternative ways to modulate a hard switched converter system. In the present work, a mathematical relationship between these two types of modulating strategies is established, using reduced forms of general AC-AC matrix converter modulation theory. The resultant modulation strategy is shown to be identical to previously reported space vector solutions, which are known to achieve minimum harmonics for both voltage source and current source inverters. This relationship is then extended to be applied to an AC-AC matrix converter, to create a simple space vector modulation algorithm for a matrix converter which can be easily implemented for real-time computation in an online control system.Keywords
