Abstract
The utility model relates to a digital power controller. The digital power controller comprises a plurality of control units. The control unit comprises a CPU, and the CPU outputs PWM waves to a CPLD. The CPLD outputs at most five pairs of PWM drive signals to a resonance circuit. The resonance circuit adjusts voltage and current values on an electroplate load. After process by a processing circuit, each path of signal of the resonance circuit enters the CPU. The CPU comprehensively processes and calculates output needed by a nest time period. Each of the control unit is provided with an RS458 interface, a CAN bus, and an Ethernet controller. The controller uses digital control and automatic adjustment to realize load current of devices in a network group, and reduces power consumption under the condition that quality is not reduced. All networking control units can realize hot plug, a PC machine is accessed in the networking devices, and office monitoring or remote monitoring can be realized through upper computer software. The control units can automatically operate normally even when the network devices are damaged or disconnected.

Fig. 2 is the utility model control module group network system figure.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1 and Fig. 2, digital power controller, comprise some control modules 1, described control module 1 comprises CPU2, and described CPU2 is 32-bit and the arm processor with floating-point operation ability.The control module 1 with networking function of take is core design, can drive the load of electroplating 24KW system.
Described CPU2 first detects unit status around, after receiving enabled instruction, according to electroplating technology, set, output PWM ripple is to CPLD3, described CPLD3 is inner comprehensively converts the maximum five couples of PWM driving of output signal to resonant tank 4 through logic and fault-signal, described resonant tank 4 is adjusted voltage and current value according to control module 1 signal in plating load 5, DC voltage after the rectification that the load of described resonant tank 4 is born and pulse current, this two paths of signals is treated, after arrangement, feed back to CPU2, every group of resonant tank 4 heat-sink temperature signal in addition, power device temperature signal enters CPU2 after treatment circuit 6 is processed, described CPU2 overall treatment, carry out overvoltage, overcurrent, excess temperature judgement, do not have according to feedback voltage current signal and PROCESS FOR TREATMENT, need to calculate the output that the next time period needs under failure condition.
Described control module all has RS458 interface 7, CAN bus 8, ethernet controller 9, can be at any time that the electroplating power supply equipment on production line is grid-connected, after control module 1 is grid-connected, can or not in the situation of main frame according to the structure that forms main frame and slave is set, all control modules 1 are slave.
Described each control module 1 forms star network by networking equipment 10, and described networking equipment 10 is router or switch.In the situation that main frame is set, the work of control module 1 in main frame automatic synchronization group, optimizes output current from system perspective, reduces system energy consumption; Any control module 1 departs from network does not affect other control module 1 operations; If use Ethernet, accesses networking equipment by computer, just can be in office watch-dog operation conditions, reduce operational management cost.
