’S FUNCTION
● Input Transformer
This input transformer is the high efficiency H dry type. This device was designed as the
output voltage corresponds to the input voltage of Inverter section and the output current
is provided enough to the rated current of Inverter section.
● Rectifier
The device is rectification section using full wave rectifier circuit, which consists of
thyristor module, cooling fin, condenser and various assembly components. This device
converts alternating electric current (AC) into direct current (DC) and provides it to the
Inverter section. The direct current (DC) converted by rectifier circuit may include some
ripple voltage. The ripple voltage is filtered with filtering circuit consisting of condensers
and good quality of direct current (DC) can be made.
● Inverter
This device consists of power transistor, cooling fin and various assembly components. It
provides rectified direct current (DC) to power transistor, and it generates sine wave after
converting the signals stored with ROM using D/A converter then inverts it into PAM type
so that it can provide power source to the load after inverting voltage and frequency into
stable alternating current (AC) source. The high-speed protection fuse is provided with
alternating current (AC) input side in order to protect this device. It was designed not to
