Transistor Type Oscillator
Our reliable drive control technology accommodates a wide range of load variations.
Environmentally friendly design delivers up to 30% energy savings compared to conventional systems.
{features}
- circuit structure
After converting to a stable DC voltage using thyristors and diodes, high-frequency power is output through a full-bridge inverter. - Output Adjusting Circuit
Output adjustment is performed by controlling the DC voltage. This method uses thyristor phase control, allowing the output to be selected over a wide range.
The circuit automatically compensates for power supply voltage variations of ±10%, ensuring stable operation within a range that does not interfere with heating operations. - Oscillation circuit/Matching Circuit
By adopting a parallel-resonance self-oscillation method, the system instantly and automatically adjusts the oscillation frequency to accommodate changes in load impedance during heating, ensuring operation in a stable phase condition.
