|
* Controller by Anders Mikkelsen
|
|
* Self-oscillating ZCS (Zero Current Switching) controller with phase-lead compensation
|
|
*
|
|
* CUSTOMIZABLE PARAMETERS:
|
|
* pvolts - Primary voltage (default: 330V)
|
|
* Adjust to match your bus voltage
|
|
*
|
|
* rlead - Phase lead resistor (default: 1k)
|
|
* Higher = less phase lead
|
|
*
|
|
* rfreq - Frequency compensation resistor (default: 2k)
|
|
* Affects self-oscillation frequency
|
|
*
|
|
* iscale - Current sense scaling (default: 0.05)
|
|
* Adjust based on CT ratio and sense resistor
