A frequency converter to power a soudronic VAA20 welding machine
… desired inverter output current and frequency. A base drive was developed to control the power transistor in the inverter. It facilitates the rapid switching of the transistors and provides them with overcurrent protection. The inverter was originally constructed in push-pull configuration. At …

Driver Based Soft Switch for Pulse-Width-Modulated Power Converters
… regular switch, only one PWM signal is needed to drive the soft switch under soft switching condition. The core technique in soft switch development is a built-in adaptive soft switching circuit with minimized circulation energy. The necessity of minimizing circulation energy is first analyzed. …
