  • Page 38: Working Procedure

    Hardware Introduction 2.3.2. Working Procedure The AC input passes the EMI filter circuit and then the BOOST PFC circuit to be converted to DC 370-410V. It then be converted to +5V, +13.5V, +12V and +24V outputs by the two-transistor forward converter. The +5V output is the main feedback output of the converter and others are auxiliary outputs of the converter.

  • Page 39: Protection Circuit

    Hardware Introduction from INFINEON company, which basic parameter is 650V/6.2A. The +5V output is the main feedback output of the FORWARD converter, +13.5V and +12V are adjusted by the magnetic amplifier, and +24V is stabilized linearly by LM317. HV is output from the BOOST converter, which uses the voltage control chip TL594 from ONSEMI company.

In the inverter module, the on-off MOSFETs are connected as a bridge circuit, which implements the on-off operations driven by the main IC and convert the input DC to high voltage AC and then transmit to the primary winding of the transformer.

  • Page 45: Working Principle Of The Regulating Board

    Hardware Introduction overcurrent. Open circuit protection: When any of the strip lamps is open circuit, the current feedback signal will be severely weak. If the feedback current does not stabilize the CMP voltage even if the voltage of CMP rises to 3V, the IC will close two output pulses and the circuit is locked for protection.
