Abstract
Disclosed is a drive system for induction motor, including a two-phase induction motor, a power source filter circuit, an H-bridge power drive circuit and a controller MCU. The power source filter circuit is configured to filter out harmonic components of a DC power source, and generate a power source midpoint voltage required for driving; the controller MCU is configured to generate a switch control signal required for operation of the H-bridge power drive circuit; the H-bridge power drive circuit is configured to generate a drive current and transfer the drive current to the two-phase induction motor; and the two-phase induction motor is configured to receive the drive current generated by the H-bridge power drive circuit.
