cuit element can be an ordinary production, power is 50W, when almost no-load power consumption, full load efficiency of about 85%, has some practical value. But its final stage power supply with floating, electromagnetic compatibility circuit can be poor. Since 200kHz carrier is not filtered out clean, distortion and signal to noise ratio and other indicators have yet to be improved.
