Title:
POWER CONVERTER
Document Type and Number:
Japanese Patent JPS61112583
Kind Code:
A
Abstract:
An AC motor drive includes a power converter (10 to 53) which supplies current to a DC bus (3) from three-phase power lines (4, 5, 6). An inverter (2) drives the motor (1) from power delivered to the DC bus (3) and it regenerates power to the DC bus (3) when the motor (1) is decelerated. The power converter (10 to 53) in turn regenerates the power to the power lines (4, 5, 6) by controlling line current such that it is substantially in-phase with the applied line voltages. Current overload protection (60 to 64) is provided for the transistor switches (16 to 21) employed in the power converter bridge circuit.
