Section 2 ─
──
─ ELITE 200 Function escription
The electrophoresis power supply is a micro controller based flyback converter power supply. The
principle sections are the primary circuit, 200W power converter, control circuit and the front panel
board.
Primary Circuit
AC power is applied through switch with EMI filter. When the switch is closed and AC power is applied,
RT1 and RT2 limit the current into the supply. BR1 rectifies the AC power to produce around 320VDC
high voltages across C3 and C . JP1 allows the line voltage selection for 110/220 VAC operation. T ,
BR2, Q , Q5, U form a regulator for the control circuitry. Q6 regulator for fan used only.
Power Converter
The electrophoresis power supply uses a 200W discontinuous mode flyback converter toplogy. When
output is needed , the control circuitry forces the shut down signal 〞LOW〞to start the power converter.
The voltage error signal is transmitted and from the control circuitry U6 to U2-9, U2 drives U1, which is
a gate transformer driver for T3. The error signal magnitude is proportion to the T3 duty cycle. When
Q1 & Q2 turns on, energy is stored in the T2 primary. At the same time, D6 and D7 conducts to charge
up output storage capacitor C18. Filter L3 and C11 suppress voltage spikes when C18 is charged up.
When Q9 turns off, snubber circuit R6 and C6 suppress the leakage inductance spike from the T2
primary winding. D and D5 help to divert current from the inductance spike. Current sense circuit CT1
active to turn off PWM if primary current exceeds 8A.
