ABSTRACT:
A solid state motor control or power control universal assembly means and method whereby common parts are used to provide two basic semiconductor power pole versions, namely, a two-terminal power pole having two semiconductors in reverse-parallel connection between the terminals and a three-terminal power pole having two semiconductors in series connections between two terminals and a third terminal therebetween. These two power pole versions are the requiste subassemblies that may then be connected in various combinations to provide the numerous different types of motor control and power control systems commonly used. Each power pole consists of two semiconductors (either thyristors, diodes, or one of each) or the like, a combination of short and/or long bus bars (two short and one long bus bar for the 3-terminal power pole; two long bus bars for the 2-terminal power pole), one long and two short heat sinks, two clamps for clamping the power semiconductors between the bus bars and heat sinks, a support for mounting each power pole on a panel, control circuit mounted on the support, and lugs for connecting such systems to a power supply and motor or other load device. A plurality of these power poles may be mounted on a panel and connected as individual 2 and 3-terminal devices. Or a plurality of these power poles mounted on a panel also include bus connectors for connecting them into various power control configurations.
