This paper proposes a design method for driving power supply for micro-power consumption lamps and explosion-proof lamps based on dual synchronous chopping mode. The driving power supply uses a single-chip microcomputer to control two switching tubes to provide working current for the main power supply and the standby power supply respectively. Bian Power Supply adopts the full-wave chopper working mode to provide operating current for the lamp group. The standby power supply adopts the half-wave chopper working mode, thereby significantly reducing the standby power consumption. The drive power supply has a simple structure, can work within a wide voltage range of - frequency, has a constant current drive function and micro-power consumption characteristics, and is stable, reliable and highly cost-effective.
With the development of electronic technology, light-emitting diodes (lamps) have gained popularity in the lighting field due to their characteristics of energy saving, environmental protection, long life and high efficiency. The sound collection part of the explosion-proof lamp is in standby state all day long, and the power loss of the standby power supply causes a waste of electric energy [-} The current standby power supply of explosion-proof lamps mostly uses resistors and voltage regulator tubes to form a simple step-down circuit for the sound collection part. Provide earth-operating current. In this way, the alternating current is rectified and filtered, and then reduced through a resistor with a larger resistance. The zener diode provides a stable earth-operating voltage for the microphone and operational amplifier, and the power consumed on the resistor is relatively small. Large, the power waste in standby is relatively large [[January.
This article uses low-power microcontroller and operational amplifier 3 to design a lamp explosion-proof lamp driving power supply that can make two parts of the circuit enter the synchronous chopper mode at the same time. The main power supply adopts the full-wave chopper mode to provide operating current for the explosion-proof lamp unit. The standby power supply part adopts the half-wave chopper mode to greatly reduce the standby loss. This kind of drive power supply has a simple structure, can operate within a wide voltage range at one frequency, has a constant current drive function, and is stable and reliable. The overall block diagram of the dual-synchronous chopper lamp drive power supply design is as shown in the figure. The circuit is mainly composed of switching tubes, energy storage capacitors, microcontrollers, operational amplifiers, and photovoltaics.
