HIGH-FREQUENCY HEATER |
摘要 |
A high-frequency heater ensures a constant breaking current, maximizes input current, and thus produces a maximum high-frequency output efficiently. In this high-frequency heater, a power supply (1) is connected in a supply line associated with an overcurrent relay (4a), and a power converter (2) converts the power from the power supply (1) to high-frequency power and supplies it to a magnetron (15). A control circuit (20) supplies a signal to an inverter controller (10) to control input current so that the input current characteristic of the high-frequency heater may become close to the current breaking characteristic with time of the overcurrent relay (4a).
