  • Simplified gate driver for power transistors
    Patent number: 9692409
    Abstract: A pulse-transformer-based isolated gate driver circuit uses a small count of high-temperature-qualified components to drive a power semiconductor switch with asymmetrical voltage biases. A differential driver generates a pulse signal from a pulse-width-modulated signal, which is passed to a charge and lock circuit through a transformer. The charge and lock circuit includes an activation path and a deactivation path, which are selectively open to current flow based on positive or negative voltage pulses in the pulse signal, to selectively turn the main semiconductor switch on or off. The charge and lock circuit can lock voltage across the main semiconductor switch to keep the main semiconductor switch in an “on” or and “off” state.
