The high-frequency generation unit (6) is configured from a commercial transformer (20), a second full-wave rectification circuit (21), resistors (22 and 23), an amplifier (24), an analog multiplier (amplitude modulation unit) (25), and a high-frequency oscillator (oscillator) (26), among others. The analog multiplier (25) modulates the amplitude of the output voltage from the high-frequency oscillator (26) with a signal wave that is in synchronism with a half-period of the cycle of the commercial power source (7)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-frequency heating device","description":"A microwave heating cooker (1) includes a high-frequency power source (10).
