ABSTRACT:
A MOSFET control topology and a physical structure for a motor control which provide a more efficient and economic DC motor control are disclosed. The control topology introduces a synchronous-rectification technique wherein free-wheel diodes are replaced with MOSFET devices that are switched on and off by a logic circuit so that they are conductive for commuting motor current during periods that the motor current supply is switched off. The physical structure and method of assembling a DC motor control eliminate time consuming assembly techniques while ensuring effective waste heat exchange between electronic components and a heat sink of the control by providing quick-install spring retainers for urging the components into heat sink conducting contact with the heat sink. The physical structure also provides for high density packing of electronic components in a controller.
