1.5 Operation Principles
APS-1102 Programmable AC/DC Power Source 1-6
1.5 Operation Principles
Figure 1-1 shows a block diagram of the APS-1102.
Figure 1-1. Block Diagram
The APS-1102 is broadly divided into four blocks.
<1> DC power source block
The DC power source block includes power factor improvement functions. The block provides DC
power sources for various devices on PCBs and for the amplifier block, while improving the power
factor of power supply input.
<2> Signal source and system control block
This block includes an internal signal source with sequence functions, and is able to provide
AC+DC output. It can also be used with added external inputs and internal signal sources. This
block also contains the user interface.
<3> Isolation block
The isolation block isolates the primary (main power source circuitry) and secondary sides.
<4> Amplifier block
The amplifier block includes a protection circuit.
