The Voltage Of The Battery Is 350 Volts And The Cart Has A Resistance Of 1,000 Ohms.

For a ten db pad (90% power dissipation), the input resistor must be sized to handle 1/2 of the maximum intended input power. Through the use of the synchronous rectifier's r ds (on) hot and its duty factor, along with ohm's law, you can calculate its approximate power dissipation: Run the resistor up with either an adjustable dc power supply, or a variac to reach the same heat sink temperature.
