Service Manual a DC voltage to PID (pin5). The striking frequency is determined by R12 and C9 connected to Pin 13(CT) and R6 connected to RSTR (Pin6).The operating frequency is determined by R12 and C9 connected to Pin 13(CT) and R7 connected to RT (pin7). DRV1 and DRV2 of U1 are used to drive U2. DRV1 and DRV2 are controlled by build-in PWM IC. U2 is switch which has two build-in IGBTs. 2.1.2) Output Circuit and Protection Circuit :( fig.

Service Manual used to discharge the waves that L850 produced. High frequency waves are damped by C852. 2.2.3) High Voltage to Low Voltage Control Circuit :( fig.6) fig.6 D850 is a rectifier in which there are 4 build-in diodes, inverting AC to DC. C854 is used to smooth the wave from rectifier. R853 is a fuse resistor to protect the following circuit when inrush current is too large. U850 is a highly integrated PWM controller.
Service Manual When Q850 are turned off, the main current flow will be consumed through D851, C875, R854 and D853. This will prevent Q850 from being damaged under large current impulse and voltage spike. 2.2.4) DC_12V and 5V Output Circuit and Feedback circuit :( fig.

Service Manual 4. Power On/Off Sequency Hardware power On/Off When power cord plug into AC socket, Power provides 16V and DC_5V. DC_5V is main voltage for panel and Regulator U101. DC_3.3V is coming from Regulator U101; DC_3.3v is main voltage for U105. When DC_3.3V input to U105 and U105 reset circuit active, U105 all registers will be set to default, that means finish hardware power on.
