System and method for driving bipolar transistors in switching power conversion

A system for driving a bipolar junction transistor, the system comprising:

• a first transistor including a first gate, a first terminal, and a second terminal, the first gate being configured to receive a first control signal;
• a second transistor including a second gate, a third terminal, and a fourth terminal, the second gate being configured to receive a second control signal, the second control signal being separate from the first control signal;
• a first resistor including a fifth terminal and a sixth terminal, the fifth terminal being connected to the first terminal, the sixth terminal being biased to a first predetermined voltage;
• and
• a second resistor including two terminals, the second resistor not being a part of any transistor;
• wherein:
• the fourth terminal is biased to a second predetermined voltage;
• the second terminal and the third terminal are connected at a node;
• one of the two terminals is coupled to the node;
• the other one of the two terminals is biased to the second predetermined voltage;
• the node is connected to a base for a bipolar junction transistor;
• the first control signal and the second control signal each are related to a pulse-width-modulated signal for a power converter;
• the power converter includes a primary winding associated with a current;
• and
• the bipolar junction transistor is configured to function as a switch related to the current.
