Welcome to the community!!

Description

Power PWM driver with voltage controlled current source for driving/suppling pulse transformer.

Pulse transformer parameters:

1. INPUT COIL:

1.1. fi wire enamelled winding = 0,35 mm (from pulse transformer datasheet)

1.2. wire enamelled winding length = 0,400 m = 400 mm (calculated)

1.3. N = 2 x 12 scrolls (from pulse transformer datasheet)

1.4. R = 0,11 Ohms (parallel 2 x 0,22 Ohms) (measured and/equal calculated

1.5. H = 47,52 uH (from pulse transformer datasheet)

1.6. U = 3,5 - 15 V DC (from pulse transformer datasheet)

2. OUTPUT COIL:

2.1. fi wire enamelled winding = 0,15 mm (from pulse transformer datasheet)

2.2. N = 1 x 300 scrolls (from pulse transformer datasheet)

2.3. R = 10,6 Ohms (measured)

2.4. U = 400 V DC (after diode one-half rectifier and C filter) (from pulse transformer datasheet)

3. OTHER

3.1. voltage insulation test at 1 kV (from pulse transformer datasheet)

3.2. dedicated frequency 33 kHz (from pulse transformer datasheet)

3.3. recommended driver IC ON Semiconductor MC34063 (1.5 A, Step-Up/Down/Inverting Switching Regulators) (from pulse transformer datasheet)

Parameters to reach:

1. PWM frequency: from 1 kHz to 75/100 kHz

2. PWM Duty Cycle: from 5 % to 95 %

3. Current: from 5/10 mA DC to 1000/2000 mA DC

4. PWM control voltage: from 0 V DC to 3.0 V DC or from 0 V DC to 3.3 V DC (whatever for now)

5. Current source voltage: from 0.1 V DC to +3.3/5.0 V DC
