| Title: |
Universal Power Module |
| Abstract: |
A switch-mode power converter uses a digital signal processor (DSP) to
control operation of power semiconductors through gate drive amplifiers,
further using the DSP's internal analog-to-digital converters to measure
necessary currents, voltages and timings within the main power circuit.
Using values captured by the A-to-D converters, software controlling the
DSP manipulates duty cycle and timing parameters of the main semiconductor
switches to provide at least three different modes of operation for
serving a wide range of lighting loads. This power system reduces the
size, cost, and weight, of circuitry needed to operate stage lighting
equipment. The DSP's microprocessor eliminates most of the complex and
dedicated analog circuitry commonly used for electronic power conversion,
and a common power circuit topology provides an identical hardware
platform for each luminaire circuit. Overall reliability is enhanced
because of the reduction in circuit complexity.
