PRM with PFC
The output of the VTM drives the PFC/PRM. The PFC/PRM (Figure 5 ) is
a microprocessor controlled, high-efficiency, zero-voltage switching
buck-boost regulator providing output voltage regulation and input
current shaping. The input voltage, isolated and adaptively
transformed by the VTM, and the PRM’s output voltage and output
current are sampled by the microprocessor. The processor uses a digital
algorithm to develop a control signal used to simultaneously regulate
the output voltage and shape the module input current, providing
harmonic current reduction. This control signal is fed to the switch
management ASIC. This provides proper switch timing, maintaining
zero-voltage switching under all operating conditions. Energy storage
is accomplished outside the PFM by means of an output capacitor that
may be sized to meet the user’s hold up requirements.
