This technical report presents the design of a Z-source inverter for an electric bike controller. The objective of this work is to evaluate the potential of using this non-standard inverter topology for a medium power (250W - 3kW) motor drive application. The Z-source inverter is able to use the shoot-through state to boost the dc bus voltage, which enables a permanent magnet motor to achieve a higher top speed. In addition to a concise review of relevant work done on this topic, this report also presents an original analysis on the switching behavior of the Z-source inverter and proposes the minimum switching space vector modulation control strategy. The design of a 1.5kW Z-source inverter prototype is detailed and the advantages of the proposed control strategy are verified experimentally.
