DEFINITION Travel Charger, NOBLE is composed of power supply part and control part. 2. Power Supply Part (Flyback Type SMPS Circuit) 2.1. INPUT CIRCUITRY 2.1.1. AC input protection circuit and rectifier circuit. - The AC input is rectified and filtered by D1-D4, C1 and C2 to create a high voltage DC bus connected to PTF1 in series with the high voltage MOSFET, Q1. - Lightning strike immunity is attained with the addition of a MOV1. - F1 and FR1 protect circuit from abnormal input current. - The inductors(L3) form a ∏-filter in conjunction with C1 and C2. - R47 damps resonances in the inductor L2.(Option) - The diode D5, capacitor C3 and resistor R6,7 comprise the clamp circuit, limiting the leakage inductance turn-off voltage spike on the MOSFET DRAIN pin to a safe value. - C7 is a Y-1 capacitor which is used to reduce common mode EMI. 2.1.2. Switching controller and transformer - Q1, Q3 and Q4 are switching controller part that uses a simple ON/OFF control to regulate the output voltage with photo coupler in secondary. - At the beginning of cycle, R4,5 are powered from a high voltage DC bus to generate the Gate voltage to control MOSFET on or off. - Transformer is composed of three windings. - W1 which connects with a high voltage DC bus. - The auxiliary primary side winding is rectifiedand filtered by D9, D11. - R9 and R10 to create a bias Gate voltage for the main power supply primary controller. 2.2. OUTPUT CIRCUITRY 2.2.1. Secondary rectifier circuit : D6, D8, C4, C5 - The secondary winding is rectified and filtered by D6 and C5. - The 5V output named as Vcc is sensed by R21 and R22 using a TL431 (U1) circuit. - Resistor R6 limits current through optocoupler U2 and sets overall AC control loop gain. - R19 is used to ensure that the programmable shunt regulator is biased at its test current. - Vpp is the voltage that rectified by D6, C3 and is used to supply drive voltage with U4.

Secondary filter circuit : L2, C6 - Switching noise filtering is provided by L2 and C6. 2.2.3. Output constant voltage circuit : U3, U4, Q2, R23-29, R35-36 - The reference voltage of output is dertermined by R27-29. - R27 is option resistor which is used as we want to change the output voltage. - Q2 keeps switching on and off in proportion to output voltage. - R35 and R36 is a up-down resistor which is used in order to adjust output voltage of about 20mV. 2.2.4. Output constant current circuit : U3, U4, R13-16, R30-33, Q5 - A constant current circuit is implemented using the OP-AMP U4 to sense the voltage across the current sense resistor R13-16. - When the drop across the current sense resistors exceeds the reference voltage appeared in pin no.5 of OP-AMP, Q5 turns on and takes over control of the loop by driving the output transistor Q2. - The pin no.11 of micom U3 operates in two, open and high. - When the voltage of pin no.11 is high, charging current is 400mA. - When the voltage of pin no.11 is low, charging current is 600mA. 2.2.5. Reverse current protection circuit : U3, Q2 - Because the Vebo and Veco of transistor Q2 is higher than battery voltage, reverse current from battery pack don't generate. 3. CONTROL PART 3.1. Micro controller : U3 - Micom controls whole charge system and includes following internal circuits. * General input /output port * A/D converter * Reset delay circuit (power on delay) * Timer - It is carried following functions * Battery recognition * Charging termination condition detection * Output short detection and output protection *Temperature detection * Output voltage & current control * Short circuit protection * Over voltage protection * Battery wake-up function * LED display * Compensation charging function REVISIONREVISIONREVISIONREVISION 1.01.01.01.0 MODEL NO.MODEL NO.MODEL NO.MODEL NO.
