Abstract

The invention discloses a stand-by circuit. The stand-by circuit comprises a voltage conversion unit, a signal detection and sampling unit, a signal amplification unit, a switch control unit, a signal comparison unit, a transistor and a relay. An input end of the voltage conversion unit is electrically connected with a main power source, and an output end of the voltage conversion unit outputs a direct-current voltage. The signal detection and sampling unit, the signal amplification unit, the switch control unit, the signal comparison unit, the transistor and a coil of the relay are electrically connected with one another in sequence. An armature of the relay is in tandem connection with a power supply circuit of the main power source and a transformer. The invention can switch off the transformer in the stand-by state, and allows stand-by power of a power amplifier to be lower than 0.5W.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a standby circuit for a power amplifier control circuit. Background technique [0002] With the increasing awareness of energy efficiency, energy saving and emission reduction in the world, improving power conversion efficiency and optimizing low power consumption technology have become the focus of the industry. At present, many countries have established relevant energy efficiency standards, such as comparative energy labeling programs and minimum energy performance. Standard (MEPS) and Energy Star standard, etc., the European Union's EUP standard requires the standby power consumption to be below 0.5W. If we use our traditional power amplifier control circuit, it is far from reaching this level just by keeping the power amplifier part in the standby state. According to the standard, in our home power amplifier, the loss generated by the transformer alone is already very l...
