Igbt Welder Igbt super-audio frequency and medium frequency induction heating equipment Igbt super-audio frequency and medium frequency induction heating equipment Main advantages: 1. The use of reliable high-power Igbt. 2. The use of voltage, current double closed loop PI regulator, thus ensuring a constant power output when the grid voltage changes. 3. The power range of 0-100% stepless adjustable. 4. The use of pulse width modulation circuit or microcomputer control regulator, regulating stability, high accuracy, low harmonic interference. 5. The PLL circuit with excellent frequency automatic tracking capabilities, with wide lock range, tracking and fast response characteristics. 6. The over-voltage, over-current, single-bridge inverter over-current protection system perfect. 7. The control circuit has a soft start and soft stop function, will not have an impact on the power grid.
