Taipei rectifier PFC Module
Three phase main voltage is applied while breaker is closed. After
Taipei rectifier PFC, soft start mechanism suppresses inrush current
to prevent any damage. A good power factor condition back to the
mains then is modified through Taipei rectifier PFC and AC voltage
is rectified to DC bus for DC-DC Section.
Full Bridge Module
The converter section converts DC voltage stored in the bulk
capacitors to high-frequency voltage by alternating the current
through switching power components. In the output side, an isolation
transformer steps up the high-frequency voltage from the converter
section and delivers it to a full-wave rectifier bridge. The rectified DC
power is then passed through a measurement section to the output
connector.
Pulse DC Module
In the pulse section, an inductor and a controlled switch are
responsible for generating pulse output from straight DC.
Output Measurement and
Feedback
The output measurement section measures current and voltage, and
feedback the voltage and current information to MCU for voltage,
current and power control and related protection.
