Dump resistors

Connection to the supply/line can be by a Diode Front End (DFE) arrangement for two quadrant operations. Addition of a chopper circuit with dumping resistor extends the operation of a DFE drive for accommodation of short term regenerative loads. More commonly for the four quadrant control required by a hoist a fully controlled bridge is used. This is referred to as an Active Front End (AFE). 

Seven module types based on crystalhne solar cells were exposed. Resistive loads kept them in operation near the so-called maximum power point with the electtical power dumped to the resistor to reduce the temperature load for the modules. 

Energy dissipater this is an element that simply dumps energy out of the system. For example, resistors and friction both dissipate energy in the form of heat...
