STARTING TRANSIENTS IN SLIP ENERGY RECOVERY INDUCTION-MOTOR DRIVES .2. FLOWCHART AND PERFORMANCE

The first part of this two-part paper described the starting transients of a slip energy recovery IM drive using the rotor rectifier and a single resistor instead of three resistors and an ac circuit breaker. The starting transient was divided into three stages; the first was the resistance starting, the second was the connection of the inverter and the third was the disconnection of the starting resistor. The diode bridge rectifier imposes constraints onto the machine equations; the relevant equations for all three stages were developed in detail. This part presents a flowchart for the solution of the system equations and presents detailed simulation results, backed up with extensive experimental verification
