Abstract: Abstract:this paper presents the design of a low-cost programmable
controller integrated circuit (IC) for general power
electronics applications. The architecture of the programmable
controller IC consists of 10-bit ADC and DAC, programmable
counter array (PCA), which is configured to function as PWM,
and a control unit (processor) for regulation. The processor unit
is configured as digital compensator, through fewer program
steps to perform accurate compensation on the voltage control
loop of the converter system. Limit-cycle oscillation is minimized
through inclusion of a sufficiently low integral gain term in the
control law. A hybrid control method is first used to control the
input voltage and current waveforms to achieve a unity power
factor correction. It is observed that the programmable converter
achieves the high efficiency power conversion. The conversion
efficiency of the digital controlled boost converter is 91% with a
0.8% ripple voltage performance. While in power factor correction
(PFC) circuit application, the power factor and output ripple
voltage of converter are 0.995 and 0.93%, respectively. The chip is
implemented with TSMC 0.25 um CMOS process.
